The most reasonable approach here, since your friends are suffering from what they think is mold issues, is for them to move somewhere else that doesn't have any mold. 

It can be rented to a church for a yard sale, a farmer for planting a garden, a parking lot for when people next door hold a party or other function.  

Home to The Ohio State University with nearly 60,000 students, 5 fortune 500 companies, over +25% population change since 2000, 2016 smart city challenge award winner gaining 50 million dollars in funding from the government, Intel is spending 20 Billion dollars to build two semiconductor plants, and many many more great things presently and coming in the future.

Originally posted by @Michael Plante:Could easily come out much higher if they ‘find’ more problems when they dig things out I would ask seller to pay And if they won’t, unless it is a KILLER deal I would move on Thanks @Michael Plante  So true...they always seem to find other things with these older homes when you start digging.....

The experience in these towns will suffer enormously if there is no one to wait tables, bump chairs at the resort, plow the roads or clean the rental rooms etc.The Town of Breckenridge just bought a number of condos at around market value, put deed restrictions on them and listed them for $160-180k less than they paid to give a few more options to locals that work 30+ hours a week in the county.

If you plan on trying to run a storage facility through 100% automation your facility will suffer a bit.

And replace 3rd or 4th generation steel worker with a logger or fisherman and you have the same mentality.. although Portlandia has gone Tech Intel is the largest employer with almost 20k employees and it appears they are going to double down on their fab plants.. the last 10 years they build DX 1 2 3 to the tune of 10B they are going to build even bigger facilities in the next 10 years.. so there is a need for about 30k homes to be built. 

Their occupancy rate suffered and eventually they all went pet friendly.5.

If the attorney you talked to is taking their side and not standing up for your position, you need to find a different attorney... one that understands your right to privacy was errantly invaded, and you suffered damages, etc.I would think someone (your attorney or you) needs to reach out to whatever entity 'owns' the police department in your area - and speak with the city / county's risk management department and start a conversation.  

We wanted to give this tenant the benefit of the doubt, but the deal is starting to feel more risky the more we move forward.The property is the perfect opportunity for us to plant our roots in a neighborhood we love, with a profitable building that will quickly appreciate.
