Currently I'm looking for some kind of methodology, software or app, that I can use to manage the properties, which will allow for another family member to step in to my role relatively seamlessly if I were to pass in the future.

It’s kind of like asking what’s the worst part about not being a real estate investor?

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

I assume any painter / handyman doing your turnover could do that kind of touch up in almost no time for almost no money.  

That’s the kind of agent you want in your corner, especially in a competitive market like San Antonio.While I haven’t worked with him directly, I’ve spoken with an investor friend who did.

Quote from @Polat Caglayan: Can you give me a few examples of where and what kind of investments I should not make?

What kinds of policies do you think might help ensure ongoing affordability as Texas continues to grow?

Pretty easy to make 2% or more when you're spending that kind of money.

This was the kind of situation where most people would turn around and walk away, but not us.

How do people work with the clause and make these kinds of deals?
