In hindsight I can see all the mistakes I made but...pura vida.I do my proformas and try to calculate returns but I don't measure the value of investments purely on these terms like some others who've responded to you.

Stock picking is gambling pure and simple. 

I have financed a number of STR properties and they will usually be appraised as a pure real estate as vacant value and a cash flow adjusted commercial value, sometime separated as going concern and real property.  

If so, and you're looking at a purely rental property (not to live in at any point) you could consider opening a self-directed IRA to invest in the new property without having to pull money out and pay penalties?

Quote from @Anderson Banegas Cerrato: Elijah, this is pure fire, man!

This is exactly why I'm asking the question, because it may be the case that some of these investors would be better off either purely treating this as a flip or just moving on from this deal if they can't flip it and get their cash back within a few months. 

The “moderate size” question is pure opinion.

Most of my clients nowadays are not pure investors.

Congrats - house hack or pure rental?

Being an LP is purely based on trust.
