I've been reading about the brrrr method and it really interests me and would give me the opportunity to buy multiple houses (one at a time of course) and be able to cash out and use the same money to buy the next property. 

I agree with you Steve Vaughan, and also Jay Hinrichs, that is a very good method to move forward in one of these situations, leniency is key, in this business, but there is a live between that and being taken advantage of. give them a time frame to get caught up and give them some social services resources to help the situation, I'm sure you will be glad you did.

Based on past caselaw, there are at least different three methods for calculating these damages. 

My preferred method of investing is and always will be rental properties.  

Foreclosures can be delayed by a myriad of methods incurring further costs. 30 day late, then they will get a breach letter stating to catch up by a certain date or foreclosure will begin.

You may need someone to co-sign on the loan, use the "authorized user" method, or be creative in various ways to get the deal you want, but it's possible.

Also what method do you use to transfer funds from your property LLC's to your 'main' LLC, do you just call it a management fee and bill the child LLC's?

My first property was a turnkey from Morris Invest, and I aim to look at the BRRRR method for a few of my next few properties.  

When that 0% interest rate period runs out, usually that cost of capital becomes VERY VERY expensive (15+ %)A more commonly used method would be to get a private loan on a note from a friend or family member.  

If you have a method of only using the 2% on this transaction then please take advantage of the conventional loan type.
