This hands-on approach enables me to obtain useful information, allowing me to make informed judgments and alter my investment strategy as needed.Analyzing these precise elements of a property gives me vital information about its potential.

we build affordable units by doing higher density and I can sell or deliver a housing unit at a lower cost by sharing common elements like slabs, hallways, centrally designed systems, etc 

There many be some gems to consider there, and the area is a growing hot spot for Phx dwellers escaping the heat for the Summer. 

Not all of our properties have central AC and most tenants will be starting to put out their window AC units in a few weeks when things heat up here in Pennsylvania.  

Basement installation doesn't make a lick of sense IMHO.Just keep the hot tub at the heated setting for winter months.

If it’s a combination heat/ac unit that runs on the older Freon and just the ac needs replacing.

Your post is confusing because an HOA cannot make a modification to a common element and then charge 1 owner for that *UNLESS* that owner or their tenants damaged the property to begin with.

Onr of my rentals origanally had a floor register for the heat with hardwood floors , I made an inlay pattern out of red oak and white oak . the rest of the floor was white oak . it became the center piece of the room . 

You take every item that will need replacement at some point - water heater, AC, heat, appliances, windows, roof, etc.

They had central heat only.
