Which one rents out fast and is in high demand around the austin metropolitian area?

You can get into a DSCR program in the high 6s depending on the DSCR ratio, LTV, Loan Amount and credit. 

Very high population growth over the past few years and sustained high rental demand along with that.

Many of your recreational campgrounds are owned by the government (either state or local) and almost all of them do not allow you to stay more than 21 days so if you are running a long term park there is a very high demand in many states. 

It is not normal to see that high in one year but it does happen too often when they need money.  

Instead of fighting the high interest rates as a borrower, take advantage of them by being a lender.

Mortgage occupancy fraud is at an all-time high right now and lenders are watching this like a hawk.

They are on the ball, respond quickly, can and will fund within 10 days if needed and I have had nothing but positive experiences with them and highly recommend them for anyone looking for a HML in areas that they lend in. 

Some gurus go as high as 70%, IMHO that is too high, leave some cushion for your private money people to sell in case you get hit by a bus.

Assuming a required rate of return of 5% (comparable to high-yield savings or a CD), the deal would need to yield a total CoC return of 10% (since everything is split 50/50).I'm stuck because while playing around with numbers, achieving this return seems improbable if not unrealistic.
