I have been able to find a couple of options for this setup though, they just require separate leases for each room and sometimes 2-3 months of rental receipts as well. 

Or would it be minus realty fees and closing costs as well?

This is a group of MTR investors who have small to medium portfolios, but we welcome new investors who are just starting out as well.

I have an STR in Niagara Falls and it does pretty well based on the purchase price. 

Also, for the new move, if you don't know the city very well, I generally bias towards renting, at least for a few months.

Some hosts also accept bank transfers, but you’ll want to ensure payments clear well in advance of their stay.

This will be costly in today's market and interest rates, but might be worth a shot if they can afford to stay.If they don't want to stay and you want the the townhome to rent to someone else and just want to assume the loan, well then she can call the lender and see if the loan is assumable. 

We have had duplexes with shared water, sewer, and trash billing, as well as shared driveways.The long term tenants act more like owner occupants, planting flowers, etc. and in some cases neighbors think that they are the owners. 

But since i rarely held more than a year all the others got paid off quickly so I did not have to do all the hidden tricks to try to fool the bank or well not fool the bank or servicer but make it harder for them to figure out I was now the owner. 

I would say that the value he brings is finding the deals, doing an initial diligence, having a local team set up for renovations/repairs/property management as well as knowledge of the neighborhood.
