Sellers worried they won't be able to sell in time before their lender takes action. 

No but keep track of those repairs as it will add to your cost basis when you go to sell it and have to pay capital gains.

They do not collect payments, but when you sell your home they will get some of your equity appreciation.

If not I wouldn't bother selling as there is an incredible amount of money lost in buying and selling properties, so you have to make sure you have a plan to maximize the equity and actually have enough. 

Try being an agent, your phone number is EVERYWHERE and you get targeted by a whole industry that wants to sell you the latest gimmick.Here is what helped me.I answer calls and when it's a telemarketer I will interrupt them and say very friendly (because I don't hate the poor person who gets paid to do this and coached to be ruthless): Hey, so glad you called, can you do me a big favor? 

Quote from @Roxanne Whitaker: Please be aware if you buy an investment property and do not live in MD, when you go to sell it you will pay an 8% tax at settlement. 

i.e. buying and selling notes.Of course the mortgage is attached to the property. 

I don't think enough people consider this aspect.Selling Stock: Selling part of your portfolio could work, but the 15% capital gains tax might make this an expensive choice unless the stock has underperformed or you’re diversifying away from riskier investments.HELOC: Using a HELOC on an existing property is a flexible and relatively low-cost option.

This is where you find the property and then you can sell it after.  

They might have a contractor they can get in do all the work and get ready to sell!
