The more issues you can take off their plate before you lock it up under contract the better you'll be.

I'm new the notes world and frankly the 3-year locked in PPR preferred return of 12% seems almost too good to be true if they in 16 years have never missed a payment or failed to repay principal.

No AI, no software no gadget, no magic pocket list, no nothing.The only way to reliably and consistently get in touch with motivated sellers is for YOU to make it extremely easy for THEM to find YOU!

I also found that if you pay people cash every day it spurs them to return more reliably. 

Most affordable developers will pay more for a given piece of property but will want to lock it up for two years under a financing contingency so that they can go through two rounds in the event their project doesn’t get awarded on their first round.  

After some investments in amenities (primarily hot tubs), our last 3 months have averaged 12k/m.This property is owned outright, and due to the size of the property, the small square footage of the units, and the lack of comps in the area we have found it difficult to lock down any refinancing.

That really isn't good enough in our opinion.Another option for you is if your property is in a realtively safe area, to install a wi-fi connected smart lock.

The BEST lenders I have ever worked with (as a borrower) are, as you say, quick to respond, reliable, honest, and never leave me hanging. 

If they replicate that kind of profit reliably, what would they need you for? 

I don't know if they will ever start construction and if they do how long will my money be locked with them.At this point, I would recommend to stay away from them until they can show some results with new constructions.In the meantime, I had invested in another syndication in the same time frame in the same Texas market.
