Update:  I shopped around a lot, and was able to secure 4.00% when my regular lender was robbing me at 4.37%. 

the way im structuring things is everything is tied into a security deposit.

@Horacio Gutierrez Like some mentioned, using Venmo is a very popular and secure way for people to transfer money instantly on their phones.

Do you like your job and just want to invest for secure cash flow for potentially early retirement?

They already gave you their social security number, birth date, income, kids' names, criminal background check authorization, etc... and they think a quick head-poke inside the front door is intrusive? 

On residential some banks will provide a working capital deposit at closing that you can use for plans, permits, etc, but they will not release the first draw until the permit has been secured. 

Personal checks for security deposit aren’t a good idea, so I would recommend not accepting them as a payment method on move in.

We’re just at an impasse of what the next step could be to secure this property. 

So we are no way experience at all.Here is the info:- 3 UNITS - 2BD/1BA - 1 UNIT - 1BD/1BA- GYM ON PROPERTY UNDER UNIT 1- SECURITY SYSTEM IN EACH UNIT WITH 3 OUTDOOR CAMERAS- POOL WITH LARGE PARTY DECK- STONE FIRE PIT- SOLID SURFACE COUNTERTOPS- ENGINEERED WOOD FLOORS- STAINLESS STEEL APPLIANCE PACKAGE-Potential Rent Calculated to be: $1,800, $2,700, and $2,800.As a noobie investor looking to get experience, I thought I would help my father move down and help run the property, find tenants, market, manage, etc. until I can systemize it and move back to Boston, MA (where we are currently located).

How do I follow through with the transaction and keep the property from going through the foreclosure process to secure the investment for me and the other investor?
