We provide a range and hot water heater and furnace/air conditioner for our rentals.

Financial condition, ability to accept risk, time alloted, expertise all play a role.

I do the same for tripped breakers, trouble-shooting a furnace or air conditioner, etc.It's free advice so take it for what it's worth.

If we get outbid at that point, it wasn’t meant to be ours, and it wasn’t a good deal.If you are new to buying houses, be sure to look at the major expense items… The roof, the foundation, the plumbing, the electrical, the air conditioner.  

Be cautious on the expenses though -- very unlikely you will ever approach a 50% expense ratio in Hawaii since there are no heaters, air conditioners, and vacancy is non-existent.    

The air conditioner was running.

UPDATE:  Tenant complained that she needs all appliances, air conditioner, plumbing, electrical, flooring and ceiling replaced (leak in the ceiling).  

You never know when your car will break down or your air conditioner will break.

I'm referring to the type that is basically an air conditioner that can be reversed and bring warm air into the house.

No additional pieces outside and it isn't those air conditioners that go through a wall like in some motels.Below is a link to the entire piece: https://www.gemaire.com/first-co-18spxa8-hp-1-1-2-...These are used as central air HVAC units in condos, apartments, etc.
