Not sure.Bottom line, while you don't necessarily need to take legal action, I would be prepared to at least understand your options, costs involved, and appropriate letters that you need to send them if they are not holding up their end of the move-out agreement.Be firm and clear on your expectations, costs to both parties, and timelines and put EVERYTHING in writing to your tenants, even if you have verbal conversations, put a letter to them summarizing it.

I'd strongly suggest getting tight with a local investor friendly lender before pulling the trigger, who will have a conversation with you rather than read a script, to ensure you aren't stuck in that hard money. 

I will send you a connection request, let us keep the conversation going!

Perhaps this conversation can shed some light on that notion.

Great place to strike up a conversation, that could turn into a deal.  

We really hit it off and had a swell conversation...Any who, let me have it!

It seems positive from the conversations we've had.  

@Tristan S. so for my personal house it was on the sellers disclosure, for some wholesale deals we've done i asked. and thats how i find out the builders. and about knowing which ones are good or not per say, that is a lot of conversations with agents, GC's, owners, a lot of google reading reviews. 

I have considered this for a property I have but it would not be a conversion it would be replacing a 4 bedroom with a duplex because it is more in line with the larger parcel of property I own and a few other reasons.
