No, if a mortgage was recorded, it would have to be paid off, or the holder of the mortgage would have to agree to an assumption, or to write a new note/mortgage with the new buyer.

You still have to use some educated guessing to get to certain assumptions - like appreciation rate and NOI cash flow etc2.

Then from there you can call local PM's to get a better feel for market rents to verify your assumption for further due diligence 

So yet again CONTEXT IS KING/KEY, because an assumption all is good because consumer spending is UP, is neglecting the fact this UP consumer spending could be leading indicator of a BAD economic standing to come, if heavily credit based. 

Doing real estate; Not an anonymous person on the internet that you can appoint titles or assumptions.

If you were either the buyer, seller, lender, or realtor in a Loan Assumption transaction in New Jersey, I'd love to connect and ask you a few questions.  

Would that standard 35-40% opex ratio be inclusive of some percentages for property mgmt fees (8-10% usually) and some sort of capex reserve assumptions?

@Angel Lomeli in our opinion, you have this backwards.Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.So, when investing in areas they don’t really know, investors should research the different property Class submarkets.

@Wesley BryantI’ll be a contrarian here…Based on 46 years in the industry…Any proforma or projection of returns are by definition based on a whole slew of assumptions the investor has little or no control over.

As it says on p.344 "make sure your assumptions are sound..."
