The initial quote I received was $1,700 to:Pump and dispose of 80 gallons of oilCut open the top of the tankFill the tank with sandCap it with concreteFor an additional $300, they offered full tank removal—which I chose to do for a total of $2,000.

For my old school investors tell me what made you initially pull the trigger?

When we bought the property we initiated a one year lease that has reverted to month-to-month tenancy at the expiration of that lease.

This will show you more evidence of the fees they really charge.

Placement can also be slower — initial approvals often take longer than placing a market-rate tenant.

No charges.

A route I can, but don't prefer to take, is to put half down on the investment with a promissory note with my partner (property fully in his name initially), and transfer the property into our LLC after I buy a primary.I greatly appreciate any help with this.

That will free up your time to make more money than they are charging.

Some of my initial research has pointed to work with real estate attorneys and tax CPAs - I am wondering if this seems accurate to anyone who has gone through this process or if you have any suggestions to aide in my search.
