My best advice is to search historic STR posts, jot down names of those you feel can provide value, and reach out.Best of luck.

The main pull of Annapolis is the unique charm of a historic town right on the Chesapeake Bay.

But, these slides from Independence Title have 5 years of data and we can look at what the market has been historically in San Antonio.

But if you said these were 100+ year old historic homes in the snow belt or on the ocean I would say the 10% is probably low. 

I have historic houses for some of my rental properties. 

Historically the Oakland market has had good appreciation and investors often refinance in less than 5 years to extract equity. 

Contact the utility provider and get an historical average based on the last year of use.

Rates are definitely going up but are currently still historically low so I would not be concerned about it being a "high" rate because it is not.

I can't speak for an industrial building but I've worked with several historic residential homes built similarly out here in AZ.In fact the home I live in was built 65 years ago and has a lot of exposed block throughout.

Good thing is (at least historically) is that over time the rents come up to balance the price relatively quickly....so if you can use a strategy to just hold a property (without being over leveraged) for 5+ years the investment will likely work out for you....IE use a large down payment or house-hacking.
