Best estimate of what a current appraisal would be.
The new reverse mortgage must be the only lien against the home.
Liens being paid off that are attributable to home acquisition and/or home improvement debt can likely be carried forward when considering what portion of the reverse mortgage accrued interest may be deductible in the future.
No longer making mortgage payments is a benefit to be considered in your retirement planning. An estimate of the deductible portion, for example, 50%, will allow calculation of the tax-equivalent monthly savings.
