If you are that individual, my humble advice is to not use a simple spreadsheet as was suggested by others in this forum.

I just closed today with an Army reserve who bought a beautiful home today and currently helping a Navy officer purchase a house hack; buy something that numerically makes sense and run with it.

@Jay Hinrichs, although as you state AirBnB is just a broker, the success of the network is affected by the actions of all individual STR owners.  

Are the units individually metered? 

Here's what I would do, step by step:I'd hop on BiggerPockets, go the the Houston sub-Forum, and find at least three members who seem to know what they are doing (based upon their profile and their posting history there).I would direct message (DM) each of the members I found and ask if they had a quick minute to give me some perspective on this listing.I'd arrange for individual phone calls.

I have raised money before, but its always been from investors that I know on an individual project basis. 

What do you all think we should do:- combine the parcels and just get a bigger loan (total would probably be around 285-300k for the loan) in order to get the cash out (about 40k)- leave it until the taxes are reassessed (probably 3.5k less then I would calculate) - refinance as individual properties-other option we are not thinking of?

I have calculated the rehab costs and vetted each individual deal to the best of my ability.

Since I have a high-risk tolerance, I'd probably invest in mostly individual stocks and some ETFS/index funds. 

The articles and posts here are super informative, but quite numerous.
