Property Nerds® / Eichler ownership planner
Explore an Eichler purchase with a mortgage estimate and a separate ownership budget. Change the price, down payment and financing assumptions, then allow for the house you are actually considering.
The starting numbers are an illustrative scenario, not current mortgage rates, property quotes or typical Eichler costs. Replace every example with your lender’s and property-specific estimates. No sign-up is required.
Your planning scenario
A / B comparison
Scenario A is your saved snapshot; B uses the current valid inputs. All figures are estimates.
| Measure | Scenario A | Current B |
|---|
Rate sensitivity
Compare principal and interest at your entered rate and half a percentage point on either side. These are hypothetical calculations, not available offers. Other inputs stay the same.
| Interest rate | Monthly principal & interest |

The Eichler part of the budget
Use the property’s inspections and service records to discuss roof, drainage, heating, slab, glazing and electrical questions. Ask qualified specialists for the scope and timing of any work. A flat maintenance allowance cannot replace that review.
Read the Eichler inspection guide ↗An archival plan can explain design intent. It cannot tell you today’s dimensions, structural constraints or the cost of a change. Separate essential work from optional design projects before putting a project allowance into the calculator.
Explore floor plans and research tools ↗Get an insurance quote for the address and ask about coverage, deductibles and exclusions. Confirm expected taxes with the appropriate local offices; a seller’s historic tax bill may not represent your costs after purchase.
Open the buyer & owner resource library ↗No. It includes only the values you enter. Separate assessments, supplemental property taxes, flood or earthquake coverage, moving costs and other expenses may apply. Loan payment totals are different from an ownership budget; HOA dues, utilities and reserves may be paid separately from your lender.
The amount and structure depend on the loan. CFPB explains that conventional loans with less than 20% down may require private mortgage insurance. Ask your lender for the applicable amount rather than assuming that a zero here means no cost.
Not necessarily. California change-in-ownership rules can trigger reassessment. Obtain a property-specific estimate and ask about supplemental bills. The annual tax example in this tool is not a county calculation or tax advice.
No. It does not evaluate income, debt, credit, loan eligibility or your full financial situation. Use the scenario to prepare questions for a licensed mortgage professional and compare their Loan Estimates.
How the estimate works: principal and interest use the standard fixed-rate monthly amortization calculation. Annual tax and insurance entries are divided by 12. Other entered monthly costs are added separately. Amounts are rounded for display.
