Hi,Once I get work completed, who should I use to verify that the work was performed well other than myself?Please let me know.

I’ll reinforce previous poster’s recommendation against aging an ADU, especially to a SFH.

Was forced to sell his home due to aging .

So Zillow can provide info like job growth, population growth, demographics (ie. median age, etc)?

I know that is frustrating, but you can't force that horse to drink as the old saying goes.My thought take a look at https://kwnextgen.org/  see if they would have any interest in that...or find some kind of meetup groups that has people their age in it or take them to a conference and see if anything sticks. 

I rent in the community and it is all-ages, and pet friendly.

I used RentPrep's TransUnion SmartMove with income verification and judgments/lien add-ons.

I guess really depends on your age also when you come into these windfalls..

Oddly, foreign national loans are very efficient as there is often limited income and employment verification. 

For properties that are in better condition and newer in age you will be able to find competitive pricing for coverage.
