Since it's not a tax lien sale, but a deed sale, we are ultimately looking to acquire the property anyway.One thing that I do need-  a good RE attorney with knowledge of Deed sales in PA, hopefully Montgomery County. 

Their responses are articulated well, on point, appears to be from a person that has knowledge of their program, and are not point and click pre scripted responses.

That means you have to purchase 4166 records to use your $125, but Datazapp is even better than every other company because of you pay them $250 in advance they will let you make as many small purchases as you want during a 30-day period until you reach 6,000 records.The cost to purchases emails and phone numbers is much more expensive when you are using a customer list you own because of what I already explained, but if you don't have a list and you want information for property owners then you can limit your lists to only those that contain both email addresses and phone numbers.I think the reason most real estate investors don't do a lot of direct mail or bulk email is because it requires a lot of software and technical knowledge.

Your irresistible offer appears to not have turned out so well either by your own admission and my advice is to help you and others reading this about the importance of knowing how and what to have in your contracts, how to properly vet buyers BEFORE you bring them a deal, etc. your situation is a great learning lesson for others and for yourself if you are willing to learn from your own mistakes.As to the assignment being legal or not, I am not 100% knowledgeable on NC laws, however, I have had several experienced investors tell me North C has similar laws regarding this process as does CA, FL, etc.

It is hard to justify an expense that would eat up all of a majority of your cash-flow.An investor doesn't necessarily need 'any' professional but it really depends on your knowledge/amount of time you have.For example, technically, most people may not need a painter as the tools are available to them in Home Depot or most stores.

Most new flippers lose money because they are not knowledgably in 3 areas What the sales price REALLY will be.

Is it worth it to potentially take a slightly smaller return on this one deal to gain the knowledge/introductions for me to repeat this process in the future acting as my own GC?

Shes a wealth of knowledge. 

Maybe as you said, its an old leak that was already repaired prior to your knowledge. 

More sophisticated and experienced investors, and those employing knowledge attorneys will understand that while not an absolute, a REG D offering offers some amount of comfort in that the sponsor has placed his offering on a more “sophisticated” level than an intrastate or general exemption offering.
