If a tenant want's to leave, they will. 

Should that be a concern that there are so many homes for rent in the area? 

Perspective is everything, but I think my concerns are pretty reasonable and Roofstock should be working to set them right.

It turns out my tenants now want to rent a month to month with a 3 month notice of leaving.

But my border collie still leaves it to growl at the mailman!

I still don’t understand the purpose of the $50k balloon.....Are you saying you’ll make monthly P&I payments to pay off $600k on a 10 year amortization instead of $650k, leaving a $50k balance?

I am considering selling the one good furnace and not run any ductwork to the apartments and replace the system with electric baseboard heat (or any other suggestions that you may have).My concern is tenant push back on higher electric bills for heat.

Why not try to approach the owner and buy the property first, you cut out several steps and a lot of time that way and then there is no possibility of the owner bringing the loan current and leaving you stuck with a note which it appears you don't really want?

Normally they just give a certified decommission by filling them with concrete or sand and leave them buried.

I recently invested some $ from my roth SDIRA into a LLC, for a multi family, but the contract fell through.Can I leave the money in the escrow account until the investor finds another deal?
