@Jeremy H.The only time negative equity matters is when you HAVE to sell. 

@Peter Lu, It's perfectly fine to sell that property and do a 1031 on your 70%. 

Whether you are purchasing your first home or the next real estate deal, closings can be a nerve racking process.

They have offered to sell this place and gift us a portion for downpayment.

As a bit of fore sight, My business partner and I plan to scale the business to have employees.I am currently paid through my llc for selling homes, but the issue is that when I am to be paid for services of property management, the funds have to pass through my managing broker's office. 

I've had to pay for some insurance premiums and some late penalties on property taxes but i can say, I've never been successfully sued in 15 years, because our process is well documented and its not a pattern or pervasive or malicious in intent (Some elements needed to sue in my opinion) if we make a mistake and, I've always made the borrower whole.

I have to say I work for the investor, not that I am a process server or courier.

Us bank played trustee and guarantor in sham of a foreclosure where they could not prove they were a PETE  and had been hit with their 4 the ftc sanction FOR stealing homes, used hole in the wall attorneys in Bellingham using typos in name and address to not get flagged for too many foreclosure by the courts, Windermere stellar real estate who say outside of my home waiting to lock me out despite supreme court stay on their theft, judge Lewis who signed every Forged/inaccurate/misleading  paper they put through AND denied my restraining order of the real estate company staying called them to see if they were harassing me and they Said no so denied temp and all together day in court altogether plus put a no Bail hold on me after looking my arrest for trespassing even though was taken out of his jurisdiction and in federal court staying paperwork not filed correctly then laughing saying I didn't know why You're here is in supreme court when I got out of jail and made it to court hearing, the assessor for king county who was on third foreclosure company because feds kept shutting them down so opened new one in different name, every process server was at least 200 miles from me and each one different for each document never served to me but judge Lewis signed them anyways(one was supposedly served to me 3 months before case was even filed), Vancouver Police department who had no jurisdiction on the civil matter that arrested me and gave my house keys to the realtor that was sitting outside waiting, and finally to the site veteran that they used to sign in all three places to transfer title and get veterans protection for title after 2 illegal auctions, one public one private, where they were only bidders and opening bid was above value of house, paperwork stated was bought by lsf8 AGAIN!!! 

Do you emphasize long-term holding of property or quick-turn buying/selling?

And of course, Lou Brown and others sell them, they don't give them away.I deal a quick google search for "Wholesale real estate contract".
