COMBINED FROM BOTH DUPLEX SO ITS ALL ABOUT PERSPECTIVE YES THIS YEAR WAS HARD AND HEART BREAKING BUT ITS ALL ABOUT THE RESPONSE AFTER GETTING KNOCKED DOWN ! 

I contacted Zillow about this issue but received no response.

Networking is also crucial for success in real estate, so look for local investor meetups or connect with others online.

@Alex V. you've got some good responses above but this specific forum is more for residential stuff. 

That's not a responsible guest.

My dude, this was the most fantastically detailed response!

Learn the lawsDon't use a contract "off the internet", laws vary by state and are also regulated on a federal level Learn the financing techniques correctlyDon’t skip parts of the processDon’t ever do a “kitchen table” closingUse the proper deedAn attorney can help you with the legal work, but the rest you are on your ownYour guru will not bail you out“Investing” in someone else’s deal by providing a small 2nd loan so the “investor” can pay for “cash to the seller” and for “closing costs” so he can do the deal is a very bad planKnow what problems can ariseLearn the responses and solutions to problems before they are needed Know everything there is to know about Title and what that meansKnow who a "protected class" individual isLearn the "back doors"Learn human natureUnderstand timelinesUnderstand regulation enforcement (some of these "mistakes" have a 10 year statue of limitations ( they can charge you 10 years AFTER you do the transaction) and carry hefty fines and possible imprisonmentThe court doesn't accept "I didn't know" for an answer"Know that the source of the lead plays a serious role in some states and federallyKnow how much of a "profit" pushes the boundaries to invite an investigationYou can be sued by the seller if you don’t do things correctlyYou are automatically at fault if an investigator or attorney or regulator gets involved.

I have had several discussions with them and there response is that if I'm not willing to pay they need to buy back the property.  

Then I mail a very simple handwritten letter and usually get north of a 30% response rate.  

.: Hi Kevin,Thanks for your response.
