Part of: Total Cost of Home Ownership

Type homeowner costs into a calculator from your loan estimate and rent roll; change one field per pass.

Inputs

Read Total Cost of Home Ownership, then enter rent, rate, taxes, insurance, and vacancy from your own documents to model homeowner costs. If the output and your budget disagree, a line item is usually missing or mistyped.

One at a time

After each run, change only one input. For homeowner costs, the input that moves monthly cash flow or equity the most is the one to verify against a source document.

Deliberate tweak

Drop modeled rent by $100/month for twelve months; if cash flow goes negative, you know how sensitive the deal is to vacancy or rent cuts.
