@Jorge Vazquez we stopped doing signs over 10 years ago.We had a separate phone number on our signs, so were able to track traffic & applications from them.We were getting more & BETTER leads from our online ads then the signs - so an easy choice to stop using them (also time & money savings).

I've just recently added a coin-op washer and dryer to a 4 unit. 

Have you done any value-added work to your current properties?

For example, Intel headquarters, Honda, Amazon, Facebook, Google, Nationwide, and recently Anduril which is adding another 4,000 jobs here!

Is the finished basement SF added to the main SF to get a total SF which I then use as I normally would to get a per SF price or do I value the basement and main floor differently?

I totally get where you're coming from—pools are such a great amenity, but they do come with some added responsibility!

.- Value-Add Investments: Beyond cosmetic upgrades, think about adding amenities like solar panels, EV charging stations, or smart home tech.

This could be added at some point.

In this market, I tend to lean towards adding value to duplexes.

Quote from @Mary Peale: May I ask which amenities you added that you believe contributed to a revenue boost?
