First off, the odds of you ever being sued for anything more than a security deposit dispute are extremely slim.

@Josh Caldwell Josh, do you think hard money strategy can be employed for securing a multi unit (4 units residential) if secured with a HM lender who will refinance the original loan after a specified period of time?

If it is nearing the end of its lifespan, just replace it.Tarp is going to look bad and will create other holes in the roof when you secure it. 

I don't have crazy high interest debt I would pay off with it or anything like that, but it seems wise to go ahead and secure the line of credit while homes are appraising so high.

Might even be able to charge a bit extra in rent for video security:)

If you do those 3 things you will be able to help them secure an investment property, make necessary repairs(at a decent price), and get the place rented and cash flowing.

We discussed a deal of using their credit to secure the loan (10% down) but I would front all the money.

For example, you buy the place and the tenant could claim the Seller allowed them to paint the walls black or that their security deposit was twice what the Seller claimed.

Includes practical advice on marketing, screening, leasing, handling lease violations, termination, security deposits, and more.

@Javaras Thomas conventional financing doesn't allow the downpayment to be secured by the subject property however, if you have other properties including your own home that has equity, you take out a 2nd on that property and use it for down payment.
