I also have a development project on a condo that is about to break ground in Mexico. 

I am just curious whether Bigger Pockets members have been actively pursuing Reno, Nevada, for investment now that Tesla has disclosed they have broke ground near Reno for their planned "gigafactory".  

It sounds like you have reason for grounds if you bought the property back in auction.

The husband would like to stay and get a roommate.My question for you is would this give us grounds to discontinue their lease if they need to move in another person to be able to afford it?

Use this experience to work out the kinks and build a strong boots on the ground team.

If it’s only some of the rooms, are they above ground on 2nd floor, ground level, or below ground?

I recommend setting your expectation of the level of cleanliness, maintenance of the yard and grounds at a very high level to the tenants.  

If anyone wants to partner up to get into some larger multi-family units, let me know. cavan, I'll shoot you a PM we do ground up multi in columbus as well as land development for larger multifamily with underpriced land 

Potential Middle Ground: Consider Renovating: Instead of selling, you could do a light renovation on the older property to increase its value and attract higher rent.

More the willing to share out reasoning and how we do it if you want to chat but the big thing where ever you go is the teams you have on the ground.
