If so, I think buying a single family home and renting out a portion of it to airbnb or a long term renter.

If they do not pay their portion (if they have one) you say, " hey you are breaking the rules of your program, if you do not pay you will " lose your free ride ". watch how fast they pay.

I just spoke with paperstac guys today and they also are doing closings now for investor transactions - so if you want to close on a note that you do not know the seller they will handle the escrow transaction portion.

So, size, location and theming to answer your question.

You will also face depreciation recapture tax on the portion of depreciation claimed while leasing the property.

Use both, square footage year built , lot size,  upgraded which year etc

This can be fairly straightforward, depending on your agreement and if a partnership return was ever filed, you'll want to report half or your portion of the basis in the property as well as half the sale price minus expenses.

I am in the process of selling a portion of the portfolio but just switching from Class C properties to less problematic Class A properties.

$125,000 to $180,000 per door depending on size and what will fit.

As far as say a vanity, always go back with at least the same size, will save you ton of work fixing walls, floors etc.
