Small units in small quantities are expensive to build.  

Are there tiny gaps between the floor boards?

And since it's just that, you were able to keep 95% of that tiny net, but X10 that is $240,000.00 so at same tax rate you have $192,000.00 net from rents.

My grandparents and parents use to do Motels so learned a quantity of 100 is always a much better price.

Then on the other end of spectrum I see the work aholics with their 60 hour or more weeks with money and migraines but little to no fun in life.Then there is that tiny percentage that has the secret sauce where they work so many hours and cap it but also make a lot of money and get the most enjoyment out of everyday.

I feel pretty good about the tax deed I bought, considering that the owner paid a very tiny sum for the property, has not financed it, has never paid taxes on it, and does not live there. 

If you're looking at just a pure financial perspective with little/no room for personal comforts, the absolute best thing you can do is live in one of those tiny homes or something like that.

And yes, I feel down, and low 7 behold, I survived, got back on, fell again, got back up, fell again, over and over getting 1 tiny % better each time. 

I have lots of cash now so no rush at all and current rate is 9% rehab loan on a tiny $155k balance so nothing too crazy.
