I look for behavior tell tale signs. 

Let's assume that the neighborhood is a C class and the median income of the city is greater than 3X of the market rent.Here are some of the considerations I've come up with so far:- Units are in need of renovation and capex is too high or not available- Unit quality is not the same as market - Seller is worried about losing tenants due to increase- Vacancy rates are high or filling units have been difficult- Rent increase would take multiple increases over multiple lease periods to get to market rate if seller is trying to retain the same tenant- Seller inherited property and just want to liquidate- Seller needs to liquidate quickly (financial burden, sickness, quick exit from land-lording)It seems like I might be missing a warning sign about a deal if they are selling with current rents that are under market; but again, this seems to be most of the properties I've underwritten.And in the same vein, what should I be worried about when purchasing a deal with under market rent with the intention of raising them after purchase. 

It's difficult to see how a tenant will be after screened and signing a lease.

Before you sign anything, definitley pin down the timeline for permitting and building.

I have been only contacting those people who sign up or request info but would like to start some cold out reach. 

If you have a potential tenant that "might not" be a good payer, just don't sign a lease. 

I just had her sign a new lease adding her boyfriend who she is alleged fighting with that starts 1/1/25 so If there is going to be a major issue id like to handle it ASAP before that lease would start. i received the messages at 2am and have not responded to him. 1.

It's difficult to see how a tenant will be after screened and signing a lease.

So how do I get out of the contract I signed?

We don't have them recorded, just signed as another layer of protection.
