re: Price per sq ft on new build home(custom build)/ how to cover my arse

Obviously need to consider how long your family intends to live in the home. What if son in law needs to take a job in another city due to layoffs or less opportunities at his company? Large homes in general sell for less per square foot than smaller homes. A customized home may be even more difficult to sell. We recently helped my in-laws purchase a home just down the street from us using a reverse mortgage purchase. They bought a $275K house and only had to pay down $110K. There are no payments as long as they occupy the house. All interest rolls over to the principle owed. They are also guaranteed to never owe more than the house value. In other words, if they both pass away and the loan balance is $350K and the house worth $325K, no money is owed if house is sold for the value. If house is worth $375K in that situation, house would be sold and estate would get $25K.
