I can’t even begin to quantify how much BP has contributed to my success and personal development.

@Matt Carey honestly man we have success just using our handyman to remove it they typically have trucks or a small trailer and won't charge that much.

The cost figures run between 10-20K with annual costs of about $500 for maintenance,  Has anyone here been successful using mound systems for flips or for buy, build, rent and hold?  

Personally I've had no success with that.

I've been doing extensive research for the past few weeks and have had no success on obtaining a Purchasing & Sales Agreement and an Assignment Contract. 

It's all about setting the buyer up for success at the start.There's a lot of systems and strategies that an investor can employ but we have it pretty locked in at 2 deals/month averaging $70,000 per deal.Hope that helps @Shiloh Lundahl, great question,Chris Pre

Most who are successful specialize.

I successfully eliminated all types of crawling pests larger than an ant from a duplex we own by physically sealing all holes that I found with caulk or even that nasty yellow gap filler stuff for larger areas. 

In all cases the comps the appraisers used obviously demonstrated the appraiser's lack of knowledge of the area, so I suspect the comment of @Josane Cumandala is correct - they're using unqualified saps who got a mail-order certificate from somewhere.In any case, there's no real defense against this.

That's why they are so "successful" at doing these type of deals.The spreads are to thin in most hot markets to be able to double close MLS deals.
