Construction is 1/3 the time, and some modular companies out there make amazing homes- very modern/industrial with lots of glass and metal and taller ceilings.

My units are roughly around 1100 sq ft and if i choose to, I could build a mezzanine, bathroom, or a ceiling fan or all of the above.

Use a flashlight and check under sinks, including shutoffs, flex lines, and waste lines; around base of toilet and at the shutoff; tub to surround and other seam caulking; faucets that leak at stem when turned on; check ceilings in every room and closet for signs of leaks (bubbling, curling or bulging paint) or staining.

The new year will also test the U.S. consumer's ability to keep spending, and fortunately, a lack of new retail construction and historically low availability rates should put a ceiling on how high vacancy rates climb in the event of a demand pullback.Here are several graphs illustrating the current national commercial retail market in The United States of America:Full Commercial Retail Market Report Here: https://d2saw6je89goi1.cloudfront.net/uploads/digital_asset/file/1183590/United_States-Retail-Capital_National-2024-01-15_compressed.pdf

I acquired a property 6 months ago and today I heard from my property manager that the ceiling collapsed.

Did I mess up by not soundproofing the ceiling or walls ? 

I have completly flipped the inside of the single family home (abated for espesdos, textured/painted new ceilings, painted all the walls, ripped up the carpet and installed vinyl wood flooring, updated all light fixtures & hardware in the home, and am woking to remodel that two bathrooms and the kitchen) and am building the Garage ADU.

There are tons of properties that are rented out that need roof replacement, foundation work, sewer relining, new furnace, etc...I've been in units with tenants living in them and tons of growth of sorts all over walls and ceilings and either tenant hasn't notified seller/landlord or they have and landlord is a slum lord.  

Gives you another (max) properties/loans you can acquire before you bump your head on the ceiling again.Now, those will be commercial loans, and your personal income will matter less.
