I expect that we will use it for a family holiday party, probably one weeks’ vacation a year and a few weekends when we can get away.

If they try and place a lien on the property and you have a signed contract by both parties documenting the scope of work in it's entirety, then you are in the right (as long as you paid them).  

Toughest part is finding the deal.

The lease is what all parties agreed to so hopefully you covered yourself; otherwise you may be SOL. 

Perhaps a nice 1950's built bungalow.Always hire a 3rd party property inspector to give you an unbiased feel for the home.

I could imagine a commercial level LVP could handle a few keg parties.  

The person you're buying from or a third party?

Also be sure that you've disclosed your relationship to all parties.

In terms of the seller financing, you just need to sell them on minimizing their tax hit in year one if they stand to make a large capital gain on the sale.

Hi Sammy, what does RMLO stand for?
