Simple answer, yes these are all normal things to utilize.However, as to how they are used - that will depend entirely on where you are going and what you are trying to accomplish.For tax purposes, given it is generally a bad idea to use an S-Corp or C-Corp for holding real estate, any other tax structure will have absolutely no difference from one another - IE an LLC taxed as a partnership, an LLC wholly owned by you and disregarded for tax purposes, owning directly, or owning through a revocable trust - all of these have the exact same tax result at the end of the day.

PPP makes no difference other than he has a penalty at the end. 

I imagine, no out of state investors see the property beforehand.

I still like LVP, but no way do I do the work anymore.

Now some people have that no problem, but others forget that when you put little down, a refinance is not a guarantee because of the LTV factor.So something to consider.

They purchased it for $3m, put $750k into it, we expect it to appraise for $5m, and are seeking loan proceeds of $3m.Here are three commercial mortgages that might be a good fit (click to enlarge, if necessary):Not listed there, but from left to right: Points are 1.25, 1.5, and 1.Prepayment penalties are 5 years, no, and no.The way to read "3/25, 15 years maturity" is that the rate is fixed for 3 years then adjusts, it has a 25 year amortization, and a balloon payment at the 15 year mark. 

However, land costs are crazy, most lots are going for no less than $400k.

I would never do that / why not broker the loan and collect a fee upfront.This is also super sketchy as no legitimate hard money lender would lend to someone who is going to lend the $ and not own the property

It was explained that they're not running a for-profit since no rent or fees are charged to the patients, the company has a large donation pool that covers operating costs and staff.

However, where utilities are combined there is no easy way to estimate the cost because there are too many factors at play.
