No need to waste time having every contractor come by in person, just ask over the phone or online how much they'll charge to tent a house your size and warranty it each subsequent year.  

Personally.

personally I would sell and buy a few more properties where your other rentals are.   

The biggest factor that cant be argued is, tankless are MUCH more efficient, if the choice was for personal residence, its easier ,  for an apartment, if it doesnt save my dollars, it doesnt make sense. 

Personally, I don't feel this duplex is worth anything even close to 199K asking price, but it's in a fantastic location where properties tend to always sell for a high value (Clarks Summit, PA) area.

Do we connect online or in-person?

James.I don't have any personal recommendations but I'd recommend checking out HomeAdvisor to find some people. 

I have 1 rental property and working on another one. recently started an LLC. what a gathered through bp/podcast. the benefits for an LLC is taxes. saying if you made $100, you spent $50 on expenses, you as the person would get taxed for the whole $100. now say you have an LLC. you made $100 and had $50 in expenses. you are taxed the remaining amount which in this case is $50. in regards to adding a property under an LLC. through a few podcast. they talked about having different LLC with each partner. so unless you want to share the pot of your first rental with your new partner, I suggest making one.
