Is there anyone in the Denver area that knows the early stages for subdividing land or what professionals I should turn to in order to start collecting some basic info?

Quote from @Denver McClure: Hey @Dave Chengoue, I'm an investor in the DFW market as well.

The capital required for Denver, and limited cash flow makes it a tough market to get your next one.

However, and I don't know anything about AirBnB in Denver, but my biggest concern for this project is the ability to consistently rent the basement for $1,800. 

In Denver metro area, for instance, the city of Denver only allows short-term rentals in a primary residence.

@Denver McClure Would be a good connection to make as he is in your area.

👀Broken down by Denver metro cities, see which month YOUR city had the highest median home price in 2024....✅ Denver - April - $610,200✅ Westminster - April - $570,000✅ Arvada - June - $655,000✅ Thornton - June - $560,000✅ Lakewood - June - $605,000✅ Englewood - July - $600,000✅ Morrison - June - $968,000✅ Conifer - January - $872,500✅ Evergreen - April - $1,200,000✅ Golden - May - $1,025,000✅ Littleton - April - $680,500✅ Parker - July - $715,000Certainly these months/time frames can change in 2025 depending on mortgage rates, inventory in your city, etc.But, if all remained constant, this gives you a ballpark idea of time of year to net the most money

My property manager called (I live in Denver) and told me they got it turned off pretty quickly, but a whole wall's worth of drywall was damaged. 

I am a resident physician in dermatology, during  medical school I bought a property in Denver with an Interest rate of 2.75% (COVID rates lol) with the goals of renting it out when I moved onto the residency.

. -- Much of Denver metro has outlawed it.
