This list isn't meant to be exhaustive — it's based on my own experience acquiring and owning residential rental properties. Every market, property, and situation is different, so use this as a starting framework rather than a complete checklist, and consult the relevant professionals (realtor, attorney, CPA, lender) for advice specific to your situation.

Buying a residential property as an investment is very different from buying a home to live in. Beyond finding the right property, you need to research the market, understand local law, model out every cost, and protect yourself legally and financially. Here's a logical, step-by-step framework.

1. Build Your Foundation: Market Knowledge and Your Team

Identify your target market

•     Choose a geographic area you're already familiar with, or commit to researching thoroughly before buying

•     Look at long-term fundamentals: job growth, population trends, school quality, planned infrastructure/development, and historical appreciation rates for the specific geography, all of which affect both rental demand and future appreciation

Assemble your professional team early — a realtor is just the start

•     Realtor: someone who understands both the market and local landlord-tenant laws, not just sales

•     CPA/tax advisor: rental property tax treatment is complex (see Section 5); get advice before you buy, not after

•     Real estate attorney: especially valuable for reviewing HOA rules, lease agreements, and local ordinances

•     Lender: get pre-qualified early and understand loan options for investment properties (see Section 6) — terms and requirements differ meaningfully from owner-occupied financing

•     Property inspector: non-negotiable before closing (see Section 3)

•     Insurance agent: landlord policies, STR policies, and CA-specific coverage (earthquake, wildfire) vary widely by carrier

•     Property manager (if you won't self-manage): interview candidates before you buy so you know their fee structure and can factor it into your model

2. Research the Market and Set Your Target Price

•     Work with your realtor to pull comparable sales ("comps") for the property type and area

•     Establish a target purchase price based on those comps — don't anchor only to the list price

•     Research the broader submarket trends (is inventory rising or falling, are days-on-market increasing, is it a buyer's or seller's market) so your offer strategy reflects current conditions, not stale assumptions

3. Physical and Legal Due Diligence

Property condition

•     Get a full professional inspection before removing contingencies — roof, foundation, plumbing, electrical, HVAC age/condition, and pest/mold issues all affect both your purchase price negotiation and your future CapEx reserve

•     For older homes, consider a sewer lateral scope and a foundation specialist review, both common issues in the Bay Area's older housing stock

Local ordinances and restrictions

•     Understand whether the property is subject to city or county rules, or both — regulations often differ meaningfully between adjacent jurisdictions

•     Check HOA restrictions specifically: many HOAs cap the number of units that can be rented, and separately restrict or ban short-term rentals entirely

•     Confirm current zoning, and check ADU (accessory dwelling unit) potential — CA's relaxed ADU laws can add significant rental income potential to single-family properties in some jurisdictions

Tenant law exposure (long-term rentals)

•     Research whether the property is subject to local or state rent control (California's statewide rent cap under AB 1482 applies to many properties built before a certain date)

•     Understand "just cause" eviction requirements, notice periods, and security deposit limits, which vary by city and have tightened in recent years

•     These rules affect both your risk exposure and how quickly you can adjust rents or turn over a unit

4. Estimate Rental Income

•     Long-term rentals: use tools like Rentometer to benchmark achievable rent based on comparable properties in the area

•     Short-term rentals: use tools like AirDNA to estimate nightly rate and occupancy based on comparable STR listings nearby

•     Build in realistic vacancy (long-term, typically 5–8%) or occupancy assumptions (short-term, varies significantly by market and season) — don't model at 100% occupancy

•     Confirm STRs are actually legal in that specific city/county before underwriting STR income at all — some Bay Area cities prohibit or tightly cap them

5. Identify and Categorize All Costs

One-time costs (at acquisition)

•     Down payment

•     Closing costs, including property transfer taxes

◦     Note: some cities charge an additional transfer tax on top of the county rate (e.g., San Jose, San Francisco) — confirm both layers apply

•     Furniture and other capital purchases (especially for short-term rentals)

•     Working capital reserve to cover the gap between acquisition and rental ramp-up (mortgage payments, utilities, etc. before the first tenant/guest generates income)

•     Inspection, appraisal, and loan origination fees

Ongoing operating expenses

•     Vacancy allowance (long-term, ~5–8%) or unbooked-night allowance (short-term)

•     Occupancy/transient occupancy taxes (short-term rentals, imposed by many cities/counties)

•     Garbage/sewer

•     Landscaping maintenance

•     Electricity

•     Water

•     Internet

•     Supplies and consumables (especially short-term rentals — toiletries, linens, etc.)

•     Permits and business licenses

•     Home insurance — confirm the policy explicitly covers tenant occupancy (a standard homeowner policy often does not)

•     Repairs and maintenance (generally 1–3% of home value annually, scaling up with property age)

•     HOA dues (if applicable)

•     Short-term rental registration/operating fees (imposed by cities and counties, separate from occupancy tax)

•     Cleaning costs (short-term rentals)

•     Property management fees (8–12% of rent for long-term; 20–40% of revenue for short-term)

•     Property taxes

•     Mortgage payment (principal and interest)

Reserve funds (separate from routine R&M)

•     A CapEx reserve for big-ticket, infrequent items — roof replacement, HVAC system replacement, water heater — distinct from routine repairs

•     A vacancy/downturn reserve to cover several months of expenses if the property sits empty longer than modeled, or if a major tenant issue (eviction, damage) arises

6. Financing Considerations

•     Decide between conventional financing, a DSCR (debt-service-coverage-ratio) loan common for investment properties, or an all-cash purchase — each has different qualification requirements and rate implications

•     Understand that investment property loans typically carry higher rates and larger down payment requirements (often 20–25%+) than owner-occupied loans

•     Model your numbers at current rates, not historical ones, and consider how sensitive your cash flow is to a rate change if you plan to refinance later

7. Insurance and Risk Considerations

•     Confirm your landlord policy (not a standard homeowner policy) covers tenant-occupied use

•     In California, separately evaluate:

◦     Earthquake insurance — not included in standard policies

◦     Wildfire/brush zone coverage — availability and cost have changed significantly in recent years in some California markets, and some carriers have pulled back entirely in high-risk zones

◦     Flood insurance — check FEMA flood zone status even if not obviously coastal

•     For short-term rentals, confirm your policy (or the platform's host protection) actually covers commercial/STR use — a standard landlord policy often does not

8. Legal Structure and Tax Considerations

•     Consider whether to hold the property in your personal name or through an LLC for liability protection — discuss with your attorney and CPA, since financing and insurance implications differ

•     Understand the tax treatment of rental income and expenses, including:

◦     Depreciation, which can offset taxable rental income

◦     Mortgage interest deductibility

◦     Passive activity loss rules, which may limit how losses offset other income depending on your tax situation

◦     1031 exchange rules, if you plan to eventually sell and reinvest in another property while deferring capital gains

9. Build the Financial Model

•     Create a pro-forma profit & loss (P&L) incorporating all revenue and expense line items above — this gives you a clear view of total cash requirements over time, not just a single year's snapshot

•     Project multiple years, factoring in:

◦     Expected rental income growth

◦     Expected expense growth (property taxes, insurance, HOA dues often rise faster than general inflation)

•     Calculate Cash-on-Cash Return by year

•     Project Net Cash Flow by year, and track Cumulative Net Cash Flow across the holding period — if the cumulative figure is negative in any year, you'll need cash reserves on hand to cover that shortfall until the property turns positive

◦     Note: in most Bay Area markets, net cash flow is likely to be negative for a number of years given high purchase prices relative to achievable rents, so the pro-forma is essential for understanding how much outside cash you'll need to fund before the property turns cash flow positive, if it does at all

•     Model at least one downside scenario (e.g., extended vacancy, a rate increase at refinance, an unexpected major repair) so you understand your margin of safety, not just your base case

10. Plan Your Exit Before You Buy

•     Define your intended holding period (5 years? 10+ years?) — this affects whether you prioritize cash flow or appreciation

•     Understand the transfer tax and capital gains implications of eventually selling

•     If a 1031 exchange is part of your long-term strategy, factor that into how you structure the purchase and hold period from day one
