Is there anyone in the BP community familiar with an arrangement like this who can help me prep my taxes this year?

Choose two days in a two hour window that you will be doing showings and let her know that you will need to proceed; point out that this is provided within her lease and that you are arranging the showings to limit any inconvenience. 

If the tenant can’t settle on an arrangement with the landlord in court, they can pay the base rent without late fees, and not be evicted.

.* Sale-Leaseback: You can consider a sale-leaseback arrangement where you sell your properties to a buyer who then leases them back to you.

Is someone looking to arranging this?

The conclusion here is that you'll be out of pocket for $74,000 - $37,983 = $36,017.If you rent, you'll pay rent only one third of the time or $56,975 / 3 = $18,992 or half the cost of buying.The difference between buying and renting is so large that it'll remain in favor of renting even if you change my assumptions.While the property might increase in value over time (or not) you'll never be able to enjoy the increase in equity since you'll keep the condo to live in it and you can't refinance.Of course, it's always nice to own your own property so that you can arrange and decorate it as you want and it might have a more homely feel.

I guess my concern is that it would create a de-facto partnership or tenancy in common arrangement, and one of the co-borrowers would be renting to themselves personally. 

LOL.. like anyone would do this for them.I would never put them on title . or give anyone like this control or ownership in any manner.. a fee based arrangement sure I can see that.. but short of that my experience over the decades is this leads to litigation with minor partner..

Tons of good oversite and security and my buyer is very happy with the arrangement as are the occupants.

You and the seller arranged this without an escrow settlement or title company?
