Ok, in the interest in offering the best advice to folks who wouldnt be asking questions if they had a professional at their disposal, please put a leash on your ego and explain the process your guys used in detail.

Any disposable money you have would be better spent buying a box of business cards and spending time at open houses, business grand openings, auction days, unlawful detainer courtroom hearings. 

Not allowing the use of personal wipes, not disposing of grease in the system, and usage of friendly laundry detergent should be enforced strictly to ensure longevity.  

Jermaine hereIf the garage disposal worked when thay moved in then the tenant pays to fix it, and that goes for the drains too.We install debris catchers in our drains you can find them at Lowe's or home depo, thay will save you a lot of headache.

Anyway, they had me keep in contact, and about once a week I'd call the executor to see how he was and he'd give me updates as to what his nieces and nephews (out of town) were considering and how best to dispose of his sister's estate.This went on for 2 or 3 months.

You may never be able to sell or otherwise dispose of your Interests.5)Rising expenses could reduce cash flow and funds available for future acquisitions.6)Our properties may not be diversified.7)The failure of our properties to generate positive cash flow or to sufficiently appreciate in value would most likely preclude our Members from realizing an attractive return on their Interest ownership.Everyone else can read the offering if they wish.

So, a tenant's disposer is leaking.

If there is any chance the tank may have leaked, then you want the Vendor to handle its removal.Inside tanks are easier to assess, empty and remove, but even then if I were to be assuming responsibility for its decommissioning and disposal, I'd discount the costs from my offer.

Hopefully, this property or another one of my properties will put me in a position to have a 100k - 150k cash line available at my disposal at all times.  

@Shaquan Whitaker if you want to do the right thing you will buy it, and then dispose of it as you wish.One thing sticks out to me "she doesn't want me to list it" are you a licensed agent?
