A HELOC calculator estimates your available credit line by multiplying your home's current value by the combined loan-to-value (CLTV) ratio, typically 80-90%, then subtracting your existing mortgage balance. For Houston, Tx, it also factors in local property tax rates and median home price trends to give a more accurate borrowing range.

Most Houston, Tx lenders require a minimum credit score of 620 for a HELOC, but a score of 700 or higher unlocks the best rates and higher borrowing limits. Some credit unions in Houston, Tx may accept 580 with compensating factors like low debt-to-income and substantial home equity.
