Just put simply, all cash means no contingencies and in NYC that's the way the game is played.

But even a hard money lender is likely going to require you to have some skin in the game. 

Is there a super spreadsheet or software out there that can handle things like:-Vacancy of single units in a multi during a rehab and the associated costs (utilities during rehab)-Projected capital expenses at a specific time...parking lot resurfacing in June of year 3-Seasonal expenses like snow removalMy point is that a percentage of something is too generic and does not represent how cash really flows.  

Real  estate is a long term game to build passive income.Skinning a few hundred bucks a door means a lot of properties.

P.s I have a couple of good friends that wholesale and I have done some myself so I know title issues are part of the game and a good title company is a blessing and earn their pay on fixing title problems.Thank 

Does anyone have any tips, techniques or experiences they would like to share on how a new real estate investor that is trying to get in the game should go about obtaining and mentor and establishing a team

You need to know the rules of the game before you can play, much less be a star. :)  

Think about what the end game looks like and work backwards to see what you need to have in terms of deal flow, cash, management etc.  

I also believe it or not have the old tried and true board games but new tech is desired. .

I have a day job as a software engineer for an IT development workshop out of Beaverton, OR.
