Still, want to send a letter to the daughter to explore this option.So I bought a neutral but kinda pretty postcard and am ready to write it and send it.

You need a neutral third party  and I am assuming your grandma would not be neutral.You can close before id'ing on day 45. 

We definitely used the full report from our inspector to negotiate with our seller at the time and it helped provide a great neutral ground. 

My properties are averaging close to a 50% increase in annual taxes.Proposed Rates (as of 5-7-19)Mecklenburg County      $0.6169 per $100  ($0.02 above revenue neutral rate)City of Charlotte              $0.3481 per $100  (keeping at revenue neutral rate)

A third neutral party will handle the escrow account money to protect the buyer and the seller.

Make sure you have plenty of money in reserves to fund negative cashflow (or neutral at best) if you for something like that. 

You can colormatch light neutral colors of flat paint for years as long as you're reasonably good with a roller.

If this was my property in the price range your asking I'd take down the weird curtains, paint the  walls with a modern neutral color like a light gray or beige. 

As far as you know, is there a point that if your rental income is high enough in relation to the mortgage payment that it could “ neutralize “ the debt service ratio?

You're not exactly a neutral third party.
