Energy (propane/electric) costs annually are atleast double to triple for an indoor heated pool, unless it is a small fiberglass insert which guests detest as they are just a little larger than a hot tub. 

I under agreement on a Worcester triple-decker where one of the unit has radiators and wonder if it is worth replacing with forced air? 

As a triple net lease tenant the property will get cleaned weekly, while making sure the property is properly maintained.

Because they all tripled quadrupled or more in price in the last 7 to 8 years  

Then the bill comes in triple what it was supposed to be for the work done, and it's all our fault.  

I would triple my estimate on that .

That's wild.Would concur to tell tenants to cancel checks if they haven't been cashed yet.Moving PMs: Don't quote me on legal ramifications of this, but if the contract with your PM has expired, triple check if you have to provide them fees/notice of cancelling the agreement.

I have been working in all of the Cleveland markets, even EAST Cleveland and have seen pricing going up everywhere double triple or more,  Heck MF are selling for 40k per unit in east Cleveland , 5 6 years ago they were 10- 15k, 

I checked and sure enough their prices on nails, H2.5s, H clips, etc were double or triple what I paid at the lumber yard.

Commercial investment with a triple net lease is passive, above median single family homes are close to passive - the lower you go in rent, the cheaper (and dilapidated) the building the more work generally.
