Even in that situation you will most likely have to front some of the expenses to get the deal closed (earnest money, deposits, inspections, etc) but can reimburse yourself with OPM equity at close. 

I recommend cleaning it up well and having professional pictures taken for advertising, schedule showings on the same day or weekend in time slots, advertise through all means you can think of: Zillow, apartments.com, trulia, cozy etc.

For example:A clear or black (if you don't want anyone to see what's inside) acrylic wall-mounted suggestion box (both of which fit the dimensions you listed and even have a slot at the top for running wires out of):Link to product: Clear Suggestion BoxLink to product: Black suggestion boxOr just a plain acrylic lockable box that comes in various sizes:Link to product: Clear acrylic boxI wouldn't think it'd need to be anything too fancy or expensive.  

I would just keep your security deposits or reserves with the bank at minimum.

You may avoid the taxes if you deposit the funds in an eligible retirement plan (which includes anIRA) within "3 years and a day" of the date of the COVID-19 distribution (note: compare to a 60-day rollover).

@Athita Covington you could have the tenant and seller sign an Estoppel Certificate where they agree that all rents are paid  up and security deposit as well.

I invoice my tenants and have created a deposit account that they either deposit rents directly at the bank or ACH them to the bank.

The repayment terms for a 401k participant loan are equal monthly/quarterly payments of principal and interest (typically prime plus 1%) over a 5 year term (longer if used to acquire your principal residence).Please note that if you take a full $50,000 and then pay back the loan, you can't take another $50,000 until 12 months after the first loan was fully paid back.Per the loan offset rules that went into effect with the 2018 Tax and Job Act: if you leave your job and the loan is current at the time you leave your job but then the loan goes into default because you left your job, you will have until your tax return deadline (including any timely filed extension) to make the loan current by depositing the outstanding balance into an IRA (and thereby avoid the taxes and penalties that would otherwise apply).Please keep in mind the multiple loan rules:Under those rules, the sum of the balances of a participant's outstanding 401k loans under a single 401k plan (using the highest outstanding balance of each loan over the last 12 months) can't exceed 50% or $50,000 whichever is less.

We signed a lease and gave the landlord our deposit.
