Making only $4000 a month for a capital outlay of $900,000+ is poor investment and so you would have to take a large discount in order for most note investors to get involved especially if these are second liens.  

I have also bought from a neighbor and such but unless you have some boots on the ground, your best bet would be finding a realtor you like and/or search the MLS. 

It could be a good investment or a poor investment.

Probably not a great bet.

I just sold a 667 sq ft new build in newark for almost $300 per square foot. the home is too big and poorly designed and finishes are very low quality inside.

Your best bet is definitely going to be a small credit union or regional bank in that area. 

If you interacted with persons in trying to understand there quoting as you communicated here, no you wouldn't get much for answers because it's demanding, condescending and with hollow threats, nobody wants to deal with that BS or person so of course they blow you off, I bet you'd blow that person off too. 

If you want formalized training, your best bet is to take a course and then network like crazy to get in the orbit of other successful syndicators so that you can see how they operate.Here are some resources:Value Hound Academy with Craig HaskellSyndication and Crowdfunding WorkshopGene TrowbridgeJillian Sidoti

If you can coordinate your purchase with the Menards 11% off Rebate Match that is tour best bet.
