I only contribute the matching 5% to my 401k which is around $6,645.00 bc it's a guaranteed 100% return.

How do you collect a security deposit for tenants that currently live in one unit of a multi-family I'm scheduled to close on in two weeks?

So your job, as the incumbent agent, is to be self-aware and discern who matches this best. 

For my particular situation I have the funds to provide the deposit in Cash and had a pre-approval letter from a private lender for this property (which is dependent on appraisal, title, and final underwriting decision), but am unsure if they will accept this as documentation or if I will be out my earnest deposit if I go for this opportunity.

However, if you are automated on locking and notifications then having the deposits distributed throughout the month would make you less anxious for that beginning of the month!

I think other things to consider is how well the population growth percentage matches the building permit percentage.

A bank is a financial institution licensed to receive deposits and make loans.

@Adah None yeah if whoever bought it also is willing to buy off MLS I could easily see an escalation clause like that if it matches what is on MLS.

Or will the seller be able to keep my deposit?

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.
