Method of delivery is irrelevant as long as you receive it by midnight on the day it is due.

My other property, I got a HELOC out on in the hopes that previous tenants were going to purchase it, but that has happened yet, so I should have done the BRRR method on that as well.

That's not really how hard money works....You can find creative methods sometimes.

In my mind if you know it is a verified email address, this would be a better method over snail mail

One thing that is really nice about this method is it takes a lot of the emotion out of the deal very early on.After you identify your target renter, look at the market and where you want to find a property.

You should look into the BRRRR method.

We have tried this method once.  

If you're going to use a "simple" method for analyzing rehab cost like the $12 a sq foot method, I would be extremely careful and particular setting money aside to go over that budget.

I will add to what @Jeff B. said:If your PM is doing a good job tenant/owner interaction only undercuts their work and very likely upsets any systems and methods they have in place.

Basically you buy 2/3/4 unit property, live in one of the units and rent the others.I used that very method on one of my properties.
