I built a pretty solid relationship with them so I suppose thats why they're offering so high for me.

Which is great from my perspective, but worries me that it is going too high too fast.

So I started looking at some land and solar websites and came up with a very basic analysis and am curious to see some thoughts.

many HML will call themselves private money lenders to give the illusion of cheaper rates and easier terms.Private money is just that individuals with funds to invest that are Private they dont hold themselves out as in the business of lending.normally this would be friends family or other high net individuals you may already know who want to do deals with you.

Is not it prudent to pay by all cash to avoid high interest rate at this time?

Any advice or responses are much appreciated.On a new build, I’d highly recommend using a gc, too many moving parts (literally) to keep track of, & if you screw something up, it could be a massive disaster. 

Where the property values are way too high to invest in.

I just got served a small claims suit because a guest thought our pet fees were too high :D

That’s a very loaded question, as it’s highly specific to your situation.

However, I'd advise steering clear of Harris County, particularly in Houston, due to the excessively high taxes.
