We have explored disposing of the asset multiple times and the same comes up during sale.  

A great thing about my team is we handle the sale and property management side for investors!

I would lean more MTR or LTR regardless of product type.

However, electing partnership or corporate taxation could be seen as a sale, causing unintended tax consequences.

One big one is that scaling the lease option sale to a homeowner will attract both public regulatory scrutiny and private litigation, perhaps class action, once it reaches a certain threshold.  

"Question: have you ever filled out a spreadsheet of cost and lifespan of each product of a property?

Ensure the state provides a clear title upon sale.

You will get plenty of that at your office sales meetings, office training, CE training, board and association training.   

Unless you are unknowledgable, my bet is you could make more from rent than sale, and still have the benefits of owning the original home while you go do something else.The 25K you have left in property will be netting you(gross) of $350 mo or 4200 per year.

This way in case of “default” we don’t need to go thru foreclosure, or bankruptcy litigation since we already own the property on a sale/leaseback/option arrangement.
