You must know what the hell you are doing and if you dont, its critical that you solicit information from people who do.

Please and thank you lovely people. 

There's a lot of fantastic people on here and tons of knowledge and wisdom to consume!

However, I'm sure many people have, especially if they have images or floor plans of the houses/other features and lots of data. 

I'm based in Dallas.Not really mate, "people buy people" and I never was a fan of "promoting" my business or selling crap from stage.But now that I think of it, might get some branded stand up banners, quick fold up picnic table, 3 pretty ladies and just have a set up in the lobby hahaJokes

Can your spouse help, kids help, relatives, one of the young people trying to get started here on BP? 

And people can do whatever they want...but most of us use lenders that will lend up to a certain point with $0 out of pocket. 

I see so many people give up within the first year because they set the wrong expectations.

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!!! 

You will need good people to help make you successful.
