A different county can mean a different home, commute and set of costs. Compare the two addresses on the same terms.
A home search can stretch from the Tri-Valley to Mountain House, Tracy or beyond. There is no universal winner. The useful comparison is the one that reflects your cash, your monthly budget, your time and the actual property.
Start with the same assumptions.
For each home, list the purchase price, down payment and loan amount. Use the same loan term and a current, written estimate when comparing financing. Ask your loan officer to explain points, credits and closing costs. A different down payment changes both the loan amount and the cash you retain after closing.
Build a complete monthly picture.
Principal and interest are only the beginning. Add property taxes, homeowners insurance, mortgage insurance if applicable, association dues and any applicable special assessments. Association dues are often paid separately from the mortgage. Ask about utilities and maintenance too. Use a property-specific insurance quote and check the tax estimate with the relevant county and qualified advisers.
Check county and property details.
Loan limits vary by county, year and number of units. Use the current official FHFA table for conforming limits, and ask your loan officer which loan program applies. A limit is not an approval or a promise of a loan. A new assessment or completed construction may also lead to a supplemental property tax bill, in addition to the annual bill.
Put the commute on the page.
Compare the real route and frequency of travel, parking or transit expenses, and time spent on the road. A lower estimated housing payment can still come with costs and tradeoffs elsewhere in the budget. For a home in an association, also read the budget, insurance and assessment information before relying on an advertised monthly payment.
Make room for what happens next.
For each scenario, show estimated cash to close and money left after closing. Include moving expenses, repairs, furnishings and the reserves you want to keep. The right answer should remain workable if a timing assumption changes or an expense is higher than estimated.
Compare your own scenarios.
Use the worksheet to explore your assumptions, then talk with a loan officer about written terms and property-specific questions. The worksheet is an educational estimate, not a quote or approval.
