The structure would be a 75/25 profit split with projected returns of 10-15% on your money in 4-5 months.

I would list the property and advise the tenants you are planning to sell. if they want to stay month to month, that's fine.

I agree with everything in this post and if it was a month ago I may have agreed with everything in this post (and I gave it an up vote).

TurboTenant offers a maintenance program for $149 annually; they will respond to tenant issues, troubleshoot, assign to a pro, and charge your card on file (unless it's over your set amount, then they will call to confirm).

I have multiple applicants that have applied. 2 look promising but both want to wait a month to  move in.

But…There’s ZERO chance I would rent by the room for $600/months more.

If it does go to probate, hopefully your brothers and you can amicably go the informal route vs formal (I've worked with families in both when buying properties out of probate and informal is FAR easier).Since there's no debt on the house, maybe you could sell with financing or maybe you could even buy out your brothers with financing -- that way you maintain ownership and just pay them a monthly amount.

The mortgage payment is $1,000 on each house, so you earn $500 per house or $2,000 monthly.

Worst case is a 3-6 month seasoning period.  

Many distributors also offer financing and can give you an idea of what monthly loan payment you’d be looking at.
