You will learn more about that deal by doing a proper demand study than you can imagine.  

Hi Cosette,I'm in the wausau area and i know a couple of good realtors but there is definitely a need for a more active boots on the ground approach or solid management here due to weather, condition/age of the properties, and proper screening of tenants(big issue in the area but getting better)If you are serious about getting something in the area definitely do your homework and I might have been through the property already probably and might be able to give some insight.

The boiler looks in good condition (although possibly  somewhat old) and heating is near instant with all radiators functioning properly, the radiators look relatively new.

3 different types of plumbing = hidden joints and connections behind the walls that weren't put together properly and will burst when you least expect it.

If the seller agreed to do any repairs to the property you will want to view the property prior to closing to make certain the repairs were done (and done properly).Also make certain the current tenant security deposits are transferred to you.

If they found someone living there after all that and took their sweet time reacting, it would be on them. 

My international RE experience is limited to South America, and it looks like I will need to build a forecast model from scratch to properly value the deal as the property and business are generational family-owned and the financials are not exactly GAAP compliant.   

Properly applying payments7.

My only issue is I want to make sure I am doing it properly.  

Depending on your lease, they did not give proper notice.
