The only things to be aware of is that the payments take 3-5 business days extra to get the money, and the background checks are decent--- but if you can, cross reference with your local district court.     

Websites like that are a trading platform.

Get a solid attorney on board, cross your T's and dot your I's.  

I find their technology platform excellent, unusual and cost effective pricing, and great responsiveness.

What I do is cross reference the decedents name to the tax records - if there is a property good lead - if not bad lead.

Investor Carrot is a great website platform designed and tested entirely to convert and capture leads way better than any cheapo (or in some cases custom built) websites out there.

If you agree to a new price then you'll have to cross your fingers over the years that your appreciation bet works out.If the seller won't negotiate a price reduction &/or  there's no appreciation play then it's just a matter of evaluating the cash on cash return for the additional $.   

It is not that complicated but you need to have a good touch in case existing utilities cross the utility trench you are digging.The best excavation operator I knew probably had 10 years of experience and he god dig an egg out of a sand pile with a backhoe (something done at backhoe rodeos).

For a major rehab I would not want that to be the platform for children to be involved.

@Joshua Simon : I sometimes "cross-capitalize" some of my properties in the way that you describe (pull money from one to pay for another.)In your specific case, I would say that you're actually bringing 75K into the deal, not 0, so you can compute your CoC return based on the 75K going in.Also, I would still account the borrowing cost against the property your borrowed from.
