You can build the tool yourself but it will take time. 

@Max Bellino For smaller properties like your 2–4 unit multifamily buildings, an online cost segregation study is a quicker and more cost-effective option, providing sufficient accuracy for straightforward properties.

– Considering Class A properties with established tenants• Less focus on appreciation – Prioritizing income stability over potential future gains Current Opportunity: I’m evaluating a retail property in downtown Portland with:• >80% occupancy, most tenants in place for 10+ years• Decent cap rate (6-7%), NNN lease• Well-maintained, high-quality building, with existing HOA which will take care of maintenance. 

I sold an apartment building and as I lived in the building was always there when my realtor showed it to prospective buyers. 

Like SWFLA  new builds  at the time I was buying for 25 to 35k at courhouse and Atlanta until the hedge funds came in and kicked us little guys to the curb. !!

Housing mix will change; more condos and co-ops and multi-family apartment buildings.

Looking to rent for $175/night min and total estimate is $100k for the build, aiming for 20% CoC.Any pitfalls/advice for this uncharted territory?

Be patient, take action when you're ready, and don't let fear hold you back—start small, learn as you go, and build momentum over time.Good luck!

However, they didn't insulate that building well so in winter residents consistently get heating bills over $200/mo. 

Assuming this is an 8 cap neighborhood you'd have a ~$420-450k value within a year (unless property taxes are crazy high) when leases would renew since it'd be valued as a commercial building with the office space.
