You might talk with a real estate/estate attorney and see if it's possible to open a probate, have a Personal Representative appointed and obtain an order from the court authorizing the sale of the property by the PR with the proceeds being deposited into the registry of the court for later distribution when all the heirs are identified. 

They collect your rent, apply late fees,  deposit your monies into your bank account, market your properties, track expenses, screen your tenants, etc for just a few dollars a month per door.  

I'd probably have better odds going to a casino and gambling.

So far it has mostly been a deposit of sand.  

You have to deposit cash up front in your bidding account to be able to bid.  

I also found out on the day we closed the loan that they have no security deposit either.

The vast majority of lawsuits against Landlords are for wrongful eviction, security deposit disputes, and Fair Housing Violations.

A cash deposit of $10,000 was required,, then a $300 a month payment till it was paid in full.

Then you will have a 10ish min quick walk through the property and if his pictures matches the reality and you don't see anything abnormal, then after you sign with him assignment agreement and you put nonrefundable deposit and close in about whatever days you agreed on(usually up to 10).  

Purchase Price:Total: $1,985,000.Deposit: $10,000 (First Deposit) within 3 days, additional $30,000 (Second Deposit) within 30 days.Seller Financing: $297,750 (15%), 5-year term, 20-year amortization, 6% interest.Balance: $1,647,250 to be paid at closing.
