We didn't know the siding needed to be replaced because it was just recently replaced by the owner before selling it to us, but probably with bad quality paint/siding. 

With the exception of building a trailer on the property (these are hard to finance), this sounds like a good plan AND if you are using it for your business AND your business pays more than 50% of the rent (if you have more than 1 tenant), then this is a more financeable property in the eyes of banks and credit unions as it would be consider a commercial "owner-occupied" property. 

We purchased the house about 3 months ago and are owner financing it.

Off-Market: I was working for a storage facility and the owner needed help removing his stuff because he was moving How did you finance this deal?

The owners name is Allen McHenry and he has transformed the property over the years.

Fractional TICs give owners the financial independence that has been associated with condos, without the need to wait for a condo conversion, a process which can take anywhere from 2 to 10 years depending on the specific requirements for the subject property.

Being albe to disect trades work that will not only meet inspection standards but exceed the investor or owners expectations. 

Weeks before closing Blue Metrix Group reached out and said they were struggling with the financing for the second park and they asked would we owner finance. 

I have a variety of contacts and I'm pretty sure I can get in touch with destressed property owners long before auction day (years before auction day actually).

I would also add that you join your local REIA chapter (Real Estate Investor Association) as it will allow you to network with other STR owners and get more location-specific information.
