The average HOA fees are about $300-$400.

You're doing 5x better than the average American. 

As one flipper I met explained to me, they look for deals where they make $50k or more, but they admitted that they get more deals from their network than they do from direct mail.My recommendation is to look at an area that has an average sale price that is lower or medium of whole area, and look in that area through the RMLS.

Maybe as a whole in the entire buy and hold industry 50% is the right average.   

I just looked up an average rate for a fourplex and chose the higher one to see if it cashflowed but I'll check insurance with an agent.Tax number was from: https://taxonline.tarrantcounty.com/TaxWeb/accountInfoTAD.asp?

Some would think this is a lot for a home in Ogden but averaged out to be $19/sq. ft. in rehab.

They averaged $1,900/mo during that time.

For my average rent of $600/month, 5% is only $30/month or $1 per day.  

The other 8 are worth -0- as the cost to rehab them is probably as much as their worth.So the maximum total value of the deal, to me, would be $450,000 for the park itself, and possibly $250,000 for the POHs, for a total of $700,000, I assumed an 8.5% cap rate on the land, and the only reason I went that low was because I'm assuming that the $150 lot rent is below market and can be immediately raised (the U.S. average lot rent is around $280).With the POHs, you can re-set that lot rent to any amount you want interntally day one, so there's some cushion there.You can possibly finance the newer POHs through 21st Mortgage, so you would get those cashed out fast if the customers qualify.

That said I’m spending probably more than the average TK buyer doing research, so either I will go all the way and put together a deal myself or I’ll get fed up with it and give up, as I’ve done several times over the past decade.
