There is only one situation that I can think of where I would even consider a tankless and that is where the current water heater location is no longer suitable (i.e. you need the space, or there is some safety concern).  

If I get to Airbnb mode I'll decorate the interior of the fireplace with candles.

But since I am still in research mode, I wanted to ask.. what is working in late 2017 here for you all?

If it is a rental add some treads for safety.

@Marian Smith  #1 most don't redeem#2 they do not have to reimburse you for improvements that were not safety/preservation oriented.  

You could also ask the bookkeeper which CPA does he/she collaborate with and then verify the competence level with with the CPA.If you are concerned about the safety of your financial documents, most cloud based accountants use software (Quickbooks, file sharing services, etc) with bank-level encryption. 

Add a cast iron or aluminum fence around the pool for safety and charge rent high enough to include a pool company to maintain...maybe, I do not have a rental with a pool (above is our pool) but I could see it being quite a plus if safe and easy for tenants.

The problem was when they all went bad, there were no safety nets...like there usually are.  

They wanted advise on how to deal with the PM Co as they understandably feared for their personal safety and wanted to move to another part of town.

I would love to know if this is a consideration and can pass along info on the model i saw.
