I've recently been looking into purchasing property using the Master Lease Option method.

At that point, you could start using the BRRRR method until you reached your goal of properties.

There was another method you can use Being that you are dealing with criminals you may wanna see about your local police station serving the paperwork ( oddly enough many do this for a nominal fee) because this will really upset these guys if they see somebody that’s in law-enforcement coming out to the house and serving the papers. it will make them very nervous and they may want to leave altogether or comply

After I get my 10th and final loan, I will definitely use this method. 

Current Situation:My offer has been accepted and I have 9 days of due diligence remaining.My Ask:Without reading “The Book on Investing in Real Estate with No (or Low) Money Down” YET...What are some methods/strategies to lower my upfront costs for the down payment, while not getting beat up on interest rates?

I would like to use the 10 conventional loans myself but at that rate I could only do 2 deals a year when you take into account the seasoning period when using the brrr method.

@Medi Sarwary I can share with you my experiance doing the BRRRR method (Actually I do a slight variation, the BARRRR method (A=Advertise, you do this for tax write of purposes if needed to write off more of the rehab cost right away.

I like this method because it limits my trips back and forth to the property, and - as John pointed out - it creates a sense of urgency in the applicants because they see everyone else interested in the property.If, on the other hand, I need to show the property to just one applicant for some reason, I will still set an appointment. 

You pick up a house put some money into it and take it all back out, you have this secret method where you can do this contentiously... forever or till you hit 10 loan but your looking for the right lady to be your wife and you'll help her get 10 loans for herself TOO!

Good looking out @Jeb Brilliant
