Another angle you could consider is to diversify into different asset classes to reduce your risk, potentially continue your low tax burden and earn cashflow passively through 1031 exchanging into Delaware Statuary Trusts (DSTs). 

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. 

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

SBA , Smaller Banks it would have be Commercial Loan sure they require something down will be required unless you have some relationships already 

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

And what I am personally seeing the Market place today.Commercial bank/ community bank were you have significant deposit relationship and long term relation ship..   7 to 10% plus 1/2 to 1.5 points.. these are relationship and experience and capacity lenders..

We'll do 25+ deals in the market so agents and GCs see an opportunity to scale and they treat the relationship with a ton of respect. 

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.

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.
