Adding paint and replacing flooring is not going to add much value in the typical case.  

ThanksThere are no plan to sell any real estate in the near term. 

You'll need either a POA or schedule an appointment at the nearest U.S. embassy or consulate for document signing - and you need to plan this well in advance!

I plan on converting the barn into another sleeping space and indoor/outdoor rec room.

I think the ultimate situation for what I described above (not the plan, but a possible outcome) could look like this:Rent main house by the rooms while constructing ADU.

Habitutal seems the better plan unless the amount owed to you exceeds what you expect they can pay. 

If you're planning an open house at a vacant listing, know that you've just let the general public know that it is just that - vacant.Better safe than evicting/repairing...

Do you know what investment strategy you plan to use in the future?

I calculated her monthly payment is 1300.Since it is a vacant investment property where she will be taking a loss at sale and has been on market for 60 days, I am thinking seller financing may be mutually beneficial.I am planning to make 2 offers:300k with conventional mortgage.

Would love to hear what you’re focused on or planning!
