I will keep that in mind when discussing the offer

The licensed plumbers do not get permits for water heaters, I have never heard of one being red tagged solely for not having a permit so I do not get permits (and know no one that does) for swapping a water heater.  

I know that Airbnb keeps getting greedier and greedier, but this is in violation of our cancellation policy.  

For example, I have a subject property that has 1682 SF on the main floor and 810 SF of finished basement (the majority of which is about 8 feet in height with the exception of some bulkheads to hide the mechanicals) and 271 of semi-finished basement that is a utility room basically (washer/dryer, freezer, hot water heater, furnace, some storage).

Planned energy-efficient HVAC installations will replace outdated ceramic heaters, reducing tenant utility costs, lowering insurance premiums, and qualifying for utility reimbursement programs—a win-win for tenants and investors alike.Inflation HedgeReal estate is historically a strong hedge against inflation.

Although for me being one a premier client of our title company they would do date downs for me for free and also keep a running spread sheet for me.

Caulking a bathtub for a plumber is the easiest job he could charge money for, short of charging to lite a pilot light on a furnace or water heater.  

@Jorge Caceres Is this with electric baseboard heaters or  heat pump/minisplits.

Right now, I do have the "REALTOR" status but wondering if it make sense to keep paying the $800/yr to keep the status?

Think that adding overhead heaters in the area of hot tub will solve the problem in colder months.
