Anyone have experience whether it is less maintance long term to replace a gas wall heater with another one like Williams brand or just go with a mini-split?

It cost about $2500 to replace the water heater.

@Rich Bultema - Just from my experience I have not had an appraiser impact the value for an older heater/air conditioner, however, a heater without A/C (as an example) has impacted an appraisal on a single family home.

In my own home the water heater is 22 years old. 4.

Lost track of when the water heater was replaced in one unit and ended up paying for the same repair twice.What's working for you?

Water heaters and boilers3.

Or are you dealing with older flooring and parlor heaters, which appeal to a different segment of the market?

Sorry to hear you replaced the same water heater twice, but I doubt better records would have prevented that. 

Size/capacity of hot water heater is also important. 

This is something I always stress and make very clear:STR investing is not just buying a property and listing it on a platform for rent.A short-term rental is essentially a hospitality asset.It’s not a hotel or a motel, but it absolutely falls under the same scope — operating a business that provides both a service and an experience to the client.Like most hospitality assets, the majority of your costs come from:• Turnover and cleaning/ Preparing the unit for the next guests                                                                                                                                           • Restocking paper towels, toilet paper, soaps, towels, linens/ Stocking up all these supplies upfront• Ongoing wear on mechanical systems — HVAC, plumbing, appliances, water heaters, etc.This is why many STR owners choose to hire specialized STR property managers — firms that already have the systems, staff, and client base to book properties months in advance.
