So that being said, can ipartner up with someone who can sign up on airbnb as a host to rent my bottom portion of the home?

Since you paid 100% of those costs and they should have covered 12 months, but you only received rent for 3 months and are now incurring an additional cost, you are entitled to recoup the 9 months portion of money lost due to the early breaking of the lease. 

Especially this size property does not typically need to meet the 70% rule to be profitable.  

I don't have anyone but myself to take care of so I am able to put a decent portion of my pay into my savings account. 

The reason I say this is because I know the facilities around us are at full occupancy for the same size unit that makeup our facility.

It is correct that the difference in a lower replacement property price, or in the cash not reinvested, is taxable as profit.Your A was absolutely correct since the price of your potential replacement was So Much lower than what you sold.In your case, the price was about $365k Less....so any profit up to $365k would be taxable, which more than your profit, so it would All be taxable, even with a 1031.Some people will keep a small portion, $20-30k of the cash received, and pay tax on that.....same scenario when you buy a Slightly lower price replacement property.

As you go up in size past the 5 you can expect the lender to take into account the property’s profitability and less on you.

This is very interesting and may save a ton of money being that their portion would be a fixed rate for 15 years.

The loan size can dictate rate meaning typically under $100K rates are not great but still reasonable.

If you want to try and find cash flow and stay in this price tier, I would look to small and mid-sized communities like Killeen, Temple, Bryan/College Station, and Corpus Christi as examples.
