Current primary residence is a 3 bedroom, 2 1/2 bath, 2 acre lot, with a fenced in, in-ground pool and 20x20 koi fish pond.

Recently converted primary residence to rental back in September.

I have a former primary residence. 

With HomePossible and FHA, you can use proposed net rental income from the smallest 3 units to help you qualify, as long as you will occupy one of the units as a primary residence. 

I currently reside in Virginia.

Primary residents, you need to make sure you are living in property majority of the year if anyone were to look into it.

You reside in a market that historically has produced one of the best ROI for buy n hold in the nation and you are considering buy n hold elsewhere. 

Bridgeton / Maryland Heights / Saint Ann.I'm hearing that studying where the residency rates are increasing along with understanding which businesses are establishing / expanding can be a great source of insight for understanding where the housing demand will be.Would love to catch you and some of the other local folks at a meetup sometime.

Could I rent it out for exactly one year, and then move back in as my primary residence after the lease expires? 

I would like to purchase a primary residence in Los Angeles, and I'm considering either selling the Seattle home when the lease is up in a year, OR using the Seattle home as collateral to get a loan on a house in LA.
