Right now I'm securing 3 lots with my own cash for Architectural review to build right after the snow melt next year.  

I had to secure a high interest split loan before the market collapsed.

Incidentally the next tenant broke the globe on it - and the mirrored closet door - and the window - phew.....security deposits... they are your friends.

@James MaherA loan is non-recourse when the lender's only security is the property.  

According to the American Land Title Association, the following types of loans do not have to comply with TRID:Home-equity lines of credit Reverse mortgages Mortgages secured by a mobile home or dwelling not attached to land No-interest second mortgage made for down payment assistance, energy efficiency or foreclosure avoidance Loans made by a creditor who makes five or fewer mortgages in a year And, in addition, 100% cash transactions (no lender involved) are also exempt.

You can always put up security cameras that record everyone going in and out. 

When posted the question,  I was more concerned with how easy/difficult it would be to secure conventional loans after having multiple mortgages.  

Im pretty sure no individual party will be able to secure a loan of this size.

From any investors whom have had experience with wholesaling high end homes please put your hand up and I would greatly appreciate your valuable time in giving me some friendly advice.My question is:  What type of earnest money deposit will 'me' the wholesaler have to put down to secure the deal with a motivated seller of a home which is over $500K and reaching to $3MM?

My professional background is in information/computing security and for many years I conducted audits of corporate information security practices/postures.
