Using a real current example on one of my investments, the home in the ~$750K range leaves me with an average mortgage of about~$3500.

I've heard https://www.rentometer.com/ a few times on the BP podcasts, although I will say that the estimated rent for my current property is about $200 higher than the range it gave me.

Expect rates in the 8.5% - 10.5% range. 

Your best bet is either find a lender who specializes in that range such as auto/boat/motorcycle, etc. or you have to go to the usual advice of a local credit union or bank that will lend from their own books. 

But, to show how useless it is, I could easily do a few cash out refis and have negative cash invested to have a portfolio wide infinite COC.)My main point was try comparing ROI or RoE it’s more “compatible”. 

Most of them have their strategy narrowed down - IE - single family vs multi, basic price range, Hold vs Flip, how much renovation they are willing to do. 

All of this will add up pretty quickly so you want to make sure that you are in a position to move forward instead of finally finding a home and being told you are $5,000 short on being able to close.3) You can look into using the BRRRR strategy.With $36,000 I would say that you will be in the price range of about $100,000 may be a little bit more.I think the BRRRR strategy would be the best option as it allows you to refinance and take your original investment (plus more if possible) and then start the process over again as opposed to having to save up another $36,000 to start over. 

Taking a discount of that number for OKC is fair so maybe closer to the $35-60k range @Rick Imby mentioned.

The house is a single-wide mobile home 2. it is a mix of residential and commercial property For a single wide home a Chattel home would be normal but the interest rate on those is so high. 

Based on my experience and talking to other investors, right now is the most difficult time to get a qualified appointment.For our team, a qualified appointment is property that fits our criteria, there is a problem to solve with the decision maker, AND within  $30-50k per unit price range.
