If your aunt isn't in a big rush, another option may be (I'm not familiar with TX law):- Pay your aunt for a Right of First Refusal (means you get a chance to buy it before anyone, but has to be notarized by you and your aunt and filed at the courthouse)- Sell your house on or off market.

If market appreciates you can get a HELOC on it or cash out refi in a few years to scale faster.

You post makes me want to remind everyone that florida isn't an easy market to enter short term rentals.

Quote from @Matthew Cook: Dig into those comps with a realtor doing business in that market.

Since I'm based in Tampa, I don't look outside and compare markets. 

There are plenty of older homes on the market that do not have closets.You need 2 egresses (including 1 that goes outside) such as a door or window, size about 70sqft (local codes may differ), ceilings at least 7ft high, and it cannot be a walk-through passage.As always, your local codes may be different.

Quick question on those who have done seller financing:- Buying a 0.3 acre downtown fort lauderdale multi family, negotiated an around 1M price w lot of development rights, double lot. seller got it way back early 90s for pennies- got good credit 800+, w2 job etc put 40% down and mortgage bank offered 6.62% 30yr fixed (CF negative as this would make current rent roll not too much compared to the PITI)- property is in ok condition, needs 20-30k repairs which seller OKd, and all 3 tenants are month to month, pay bit under market but also ok- seller would like to do seller financing, interest only at 5.75%, 30yr amortization at 7yr balloon (CF would be positive) - id be paying some principal as well, just to grow some equity- buying this deal for the future development of the area (las olas, kushner broward crossing) so not really worried even if we overpay for it now, but never done creative finance as i always relied on a strong W2 job to get good loans but obv im used to 3% 30yr rates from covid times not this 6+ environment..Goal is to hold the property 3-5yrs, and then actually develop it or sell half the land / refinance, pull out HELOC if it appreciates.Questions:1) What does he know that i dont? 

If things go sideways, you discovery greater rehab expenses, the market takes a turn for the worse, you can get in the red quickly. 

Note at “standard” MLS market rent to price ratio, the property tax alone is ~20%.

Plus how did he go there he must live there or close so your only working one market.
