I've found a few lately with nuwber that supplement the ones you are currently using.More for residential than for commercial I think are some of the database/CRM providers like Mojo and Deal Machine.

He had sold a house to a woman on a land contract and her balance was $31,000 and was paying just under $500 per month PITI at 11% interest.

I've been working with her...I know, probably a mistake (sigh)…but I'm in a soft rental market and she does at least get the full rent paid (plus late fees), albeit in pieces.As an aside, wWe had a "Come to Jesus" talk and supposedly she is looking for a p/t job to supplement her expenses. 

There is also a supplement homestead exemption for 25-35% depending on the home value.  

Did you partner with a GC to supplement for lack of previous GUC experience or were they willing to sign a guarantee?

However, I got into real estate investing as a mean to supplement my income to pay for school and get out of debt.

Essentially CA supplements your property taxes.

This is straight cashflow of course which is nice, but you want to roll this into more cashflowing real estate assets, not leases.This business model supplements my buy and hold rental portfolio nicely.

For example, I might use it to fund or supplementally fund a fix and flip project, or a BRRRR investment.

So far, I've done a good MTR business to supplement my STRs, but they have been primarily contractors and travel nurses.
