Compare total monthly cost, not list price
Two condos at the same list price can produce different monthly bills when HOA, tax, insurance, and assessment risk diverge. Buyers who sort by price alone often choose the building with thinner reserves or harsher insurance terms.
Build one spreadsheet row per building with the same down payment, interest rate, and hold period. Only the association-specific lines should change.
Normalize financing assumptions
- Use the same down payment percent and interest rate for both units
- Use the same loan term unless one building requires a different program
- Add PMI if either scenario is below 20% down
- Include closing cash so you compare liquidity, not just payment
Start with our condo cost calculator or monthly condo expenses calculator for each building.
Add carrying costs line by line
- Property tax modeled on your offer price in each county
- HOA dues from the current budget, not the listing
- HO-6 premium matched to each master policy
- Utilities, parking, and storage if billed separately
- Monthly assessment buffer or spread cost for disclosed projects
Stress-test HOA with our HOA fee calculator and pending assessments with the special assessment calculator.
Read reserves and building age
A lower HOA fee with 25% funded reserves can cost more over five years than a higher fee with a funded roof line. Building age drives facade, garage, and envelope cycles that young townhome HOAs have not faced yet.
Use our reserve study guide and underfunded reserves guide while comparing packets.
Compare the rent alternative
If monthly ownership is close to rent for your planned stay, run the rent vs buy calculator with the same hold period. A cheaper list price does not help if you need to sell in three years and transaction costs erase the edge.
Read how long should you stay before buying when breakeven looks longer than your job or family timeline.
Choose the less fragile option
The winner is not always the cheaper payment today. Prefer the building with funded reserves, clean inspection status, and insurance renewals you can understand—even if the monthly total is slightly higher.
Frequently asked questions
- Should I compare condos in different states the same way?
- Yes—normalize tax, insurance, and HOA inputs, but read each state guide for reassessment and master policy rules that change those inputs after purchase.
- What if one building has lower HOA but a pending assessment?
- Add the spread assessment payment to monthly cost. A pending roof project can erase years of HOA savings.
- How much HOA increase should I stress-test?
- Many buyers model 10–20% dues increases when reserves are thin or insurance minutes show renewal pressure. Use your own comfort margin.
Sources to verify before buying
Use this checklist during due diligence. Calculators help you plan; these documents tell you what a specific building actually costs.
- HOA budget and audited financials (or reviewed statements if the association is small)
- Reserve study with percent-funded and component schedules — often prepared under CAI / APRA standards
- Master insurance declarations: carrier, deductible, wind/hail sublimits, and coinsurance
- Board minutes covering the last two insurance renewals and any assessment votes
- Written special assessment notices and payment plans
- County assessor or municipal property tax estimator for the parcel (not a neighbor’s bill)
- HO-6 quote aligned to master policy gaps — confirm with your state Department of Insurance licensed agent
- Lender condo questionnaire or Fannie Mae / Freddie Mac project review status for warrantability
