I'm trying to get financing lined up before I find a deal. I want to do a seller financed deal that allows me to put less down, but I still have to come out of pocket the rest of the down payment and construction cost...

Depending on the application, first, last, security, and another month or two.

This also creates quite a level of security for our clients, especially seeing Several builders in the BTR space go sideways over the last few months and we are currently trying to help several investors stuck in building projects that are only half built.  

To stay secure, I’d recommend saving 3-6 months of mortgage payments, budgeting for repairs, and possibly investing in a home warranty.

The portal is not secure. 

Also, right now we are utilizing FB but we may change this next year to a platform outside of FB for better interaction and more security.

Ironically the property does not have an official address.

Agree with @Jeff Pollack on having the guts to leave the security of a JOB.

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

The lender lent based on them being one thing which secures the debt.
