The remaining 3 units are occupied by the owners, the owners adult child reserves another unit and the 3rd is basically storage.I'm thinking long game here, but how/where do you start the approach?

Hello Clarence, You can potentially have 2 FHA loan simultaneously with some exceptions (buying for elderly parents whom could not otherwise afford a home on their own or for a child who is disabled).

The child needs paint/maintenance/constant education of the parent.

I wonder how any of you would feel when some strangers tell YOUR child on how/what/when to do things?

This will not factor into it.Now, hypothetically if someone had things like child support payments, government liens, that could affect their chances of qualifying since child support payments usually factor into reducing their monthly disposable income.

Due to the pursuit of family stability, with a growing child and a desire to build connections in the neighborhood, we will be moving to Georgia in the beginning of March for the latest.I am excited about continuing my real estate career in Georgia, not only as an agent but also as an investor.

the Child gate, alarms, etcThank you BP! 

With a Series LLC, you might have more cost initially, but after that you can create child series with an internal document.

Re: second part of your post - Many conventional mortgage lenders do not offer it, but Fannie Mae technically will allow you to purchase a home for a disabled or unemployable parent or child to live in under more lenient guidelines.

One of the properties had just an alarm but we installed a fence.One year ago we had an incident where a guests' child almost drowned in our pool.
