Closing deals also is a huge confidence booster.

The 50 gallon with booster would probably work too.  

Well water pressure is not what people are used to and you may get complaints without a booster pump.   

My husband and I are working on getting financing lined up for our first rental property purchase.  We worked so hard to pay off our home and have absolutely no debt.  The idea of "good debt" seems very counter-intuit...

If the pressure is not what you desire you can always install a booster.

This is a huge confidence booster.

Stop thinking replacement and think of it as a booster or turbo.

If you have the option a mini-split can be used in a bigger space with ductwork already in place and a booster fan.

If the wires are all there and functioning and you can mark where the jacks would be (photo of the room with an x) saved in a file then you may as well leave the wiring just in case a potential buyer wants them.Internet wiring if it is there could be beneficial to place boosters and or allow people to wire in smart tv's or whatever fun devices they come out with in the next decade.

UPDATE:First off let me say thanks to everyone who posted on here and for all the confidence boosters!!
