The second one to build a security net.I've simplified the deal a lot but... am I missing out something obvious?

When its included in a lease for real estate then the laws pertaining to residential rental security deposits in your state apply but when its separate you should have more leeway to get some additional deposit to protect you.

I will secure the loan for everything.

Securing Lending shouldn't become a hurdle is the Deal numbers works. 

I should have been more clear...I actually have a BLOC with multiple properties securing the interest.

When rates re-trace and other folks start trying to deploy the capital, I want to know I secured the (right) asset.

Sellers may struggle to mentally shift from "owner" to "tenant," which can create challenges with boundaries and property care.Security Deposit:If you’re doing a temporary leaseback, be sure to collect a substantial security deposit to cover potential damages and ensure they vacate on time.

With careful planning, you can develop a portfolio that consistently outpaces inflation and helps secure your financial future.I hope this helps.

Quote from @Matt Meier: Good morning,I’ve come across a renovation property available at a significant discount and would like to secure it without going the traditional 6-month financing route.

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.
