Any grandfathering will be lost when one of those tanks fails. 

They all use the same Real Estate Agent as well and she is a shark. 

Last I would see if there is a record of an oil tank.

The tax advantages of buying/holding gas stations are pretty great.Many of the components of gas stations including pumps, tanks, external parking areas, and other equipment are classified as either 5 or 15 year property so you can bonus depreciate a lot of it (minus the land value) and get significant deductions in year 1.With the 2025 bonus depreciation rate at 40%, a $1 million gas station acquisition could still lead to $100K+ in year 1 deductions depending on the specifics of your deal.

Let's say you're paying 3 points and 12% to a real shark. 

3) Washer/Dryer/Water Heater Tank: The house has a space tucked away for a washer/dryer, vents and all.

Sixteen homes to inspect- roofs, hot water tanks, soft floors, siding damage, decks, porches, furnaces. 

An example of one package we have is a Romantic Package - $199. 12 Balloons (buy the helium tanks and keep balloons on site for your team or use a local shop)Rose Petal Entry Way (bought off Amazon)2 Dozen Roses (local grocery store for $10-15 each dozen)Led Candle Display (bought off amazon and reusable)I Heart U Signs (amazon and reusable)Champagne (or wine if they want)This equals around $60-70 each time and we pay our cleaner $40 to set up.

Why intentionally put yourself in the tank with the potential of that deficit being much wider than you anticipate?

Soprano the loan shark down the street.
