Along with negotiating the feasibility period and due diligence periods I'd concurrently do 2 things based on your plan:1. talk to the solar companies in the area and understand their site selection process, how they structure their deals, how they operate, etc. 2. talk to the power company and see if they need more renewable energy and if building another solar project in that area makes sense. 

The main items in our renovation are:New water main from curb and valveNew electric service and panelAdd bathroom + convert to full bathLVP in 70% of the houseInterior PaintingAdditional bedrooms in basementKitchenette in basementEgress(x2) in basementOur scope of work should create a great living space for us to grow into, but also provide a rental unit that competes (or even exceeds) the area offerings for medium term rentals.

Real estate had it's reckoning and it's timing, if you didn't get into it and you ever invested in physical assets with size(i'm talking infrastructure, energy, etc.) you'll realize most of these assets are never intrinsic(ITM).

Meaning listing a home for sale will require MORE actions, efforts, energy, intelligence.     

Do you want to put all the money, time, and energy into owning this home/investment?

If he was doing minimal renovating in this scenario (obviously no electrical wiring etc) is he required a contractors license?

Take into account elements including the property's state, the age of the HVAC, electrical, and plumbing systems, and any necessary cosmetic renovations to draw in renters.

Could offer competitive pricing compared to the laundromat, with added convenience that it is on premises and laundromat does not take cards.First step is to get a quote on bringing plumbing (and electricity) to this utility closet.

I can give general estimates on most costs with regard to roofing, HVAC, electrical, plumbing and foundation, etc.

i bought a home warranty once and never would again. they rarely have things taken care of in a timely manner, which can be fine for your primary in some cases, but not for a rental. and the companies they contract to do the work, are getting paid pennies on the dollar for those jobs based on the deal they negotiated, so they're in NO rush to get out to you. and like any insurance company, they do all they can to get out of stuff. it was a waste of not only money, but also time and energy.
