Ideally, a janitorial service would clean the common bathroom, but in the area where this property is located, it generally falls to the tenants' goodwill to collaborate in the cleaning process.

Numbers look good. Will

Many people try the "Good Will Hunting" approach: [“You wasted $150,000 on an education you coulda got for $1.50 in late fees at the public library.” ?

Goodwill letter?

In relation, the contract was $10k on the 4-story building that was being torn down with a crane in Philadelphia that recently made the news for collapsing on the neighboring Goodwill store and killing 6 people. $10k for that kind of demolition struck me as cheap, and perhaps it was a cut rate contractor.

No commissions due if one of those buys it.So now you are only into "goodwill" compensation.

One of our guys still has the same problem.He rented his property to a church for refugees.Bedbugs galor.He found out that the bedding they gave them was from the local goodwill store???

I've got a certain quote from Good Will Hunting I'd like to put here but its got some cursing

They will probably not really have any idea what you just said but 2 key things just happened, you disclosed your intentions which insulates you from the unlicensed RE possibility, and you may have earned some good will with the seller because to them that $500 will be a savings and that is to their benefit.

Jon Holdman has a good point regarding the value of goodwill ...but you may also want to throw in a non-compete within a certain mileage/county etc radius.An interesting concept keep us updated..Good luck
