I LOVED getting a loan through DR Horton on a DR Horton build, that I had to pay for a DR Horton appraisal.

If not, who do you believe the natural buyer is and why do you believe they will pay retail when they can replicate what you accomplished with any number of available properties on the market at any given time?

Things just require more ongoing expenses percentage wise out of state because you have to pay people to do everything for you and you will have a longer time building relationships with vendors even when getting decent referrals. 

But this was an awesome opportunity for me because this is my first living situation where I will be on my own (and getting used to paying a rent/mortgage) but this will put my overall mortgage on a 400k house at roughly $2000 a month for the first year!

I ran some of your numbers, assumed rent of $1,290/unit and that you pay cash for the rehab costs.

I noticed that the previous owner let them pay half the security deposit and the other half later, which is a red flag.

You don't provide enough data to know.Every product is only worth what you are willing to pay for it. 

There are many reasons why I haven't pursued the arbitrage model, but mainly that it takes too long for the ROI after investing all your time and effort into buying furniture and renting and paying utilities.Let's say you rent an apartment for $1500 and you spend $7000 to furnished it.

So she got Airbnb to refund her for almost 3 weeks of the pay that she gave me And she stole a chair from my room that was crazy

I’ve even priced several models from different manufactures and found what I think would be the perfect piece of land to where if I could get the funding my bigger plan was to divide about half the acreage into 8 or 9 parcels which would be enough to pay back the investors/loan and then take the other half of the acreage and place tiny homes around each on their own couple acres.
