Is it pretty common for larger mutlifamily to have big AP?   

Hey, seeing who has experience moving mobile homes.

Property prices are very high in this region, and it seems unlikely that rental properties will generate positive cash flow due to the high cost of homes and current high interest rates.

Leverage magnifies return. 3) The effort involved in adding an ADU is comparable or larger than a rehab associated with a BRRRR.

That meant that those same buyers could no longer afford a home in Norwood, Reading or Braintree. 

A 1,767 SF (Living) for $369,900 and a 1,767 SF Pool homes for $479,000.

I bought a house with cash from pulling a heloc on my home, off market, unappraised (deal was a no brainer in a great part of town.) 

Not sure if they would review a larger multifamily, but I'm guessing you can start with them and they may have a suggestion.Good Luck!

If you don't own the home today, you can't do that. 

Even though it's private the sellers note will be recorded as a lien against the home.
