Im ideally going to be starting my own property management company for small "boutique/aesthetic STR's" in the Lakes Region of NH. 

Not a red cent, so get over the “new” aesthetics and get a good painter who either repairs or has a guy who repairs and get a bid!  

Nothing structural, but more than just aesthetic changes.

Think brick, stone, wood siding, and other costly aesthetic requirements.

A good property manager will be able to help you with this as they should have a good pulse on the market for the aesthetic demand of things.Also, you can ask your contractor if they have someone or work with someone who aids them with design of things.

We will be doing some aesthetic improvements before renting, and furnishing one of the units for midterm rentals. 

So to be a bit more clear, we are not looking for more land to "build" on, we are looking for an aesthetically pleasing atmosphere for our permanent and temporary RV tenants.

@Aroldo Villarreal Cash Flow and CAP Rate/ROI.Ratios are fantastic, but I would focus more on the location, aesthetics, and quality of tenants you can attract on the property.

They say that they are factory built homes, but that they rival any site-built home for aesthetics, and are superior in terms of quality, value and time to construct.

Whereas, if you looking to save money and more aesthetic roofing option you can opt for modified bitumen roofing.
