It's important to carefully consider your options and what will best help you achieve your long-term goals.

So I am considering two options:(1) HIre a contractor to hand off to finish the project.(2) Sell it as-is.If I go with option #2, obviously it cannot be a normal sale as the property is not habitable in it's current state, so cannot be mortgaged nor insured. 

Frinee,I do have the option of paying it off with Roth 401K funds, which would mean 0 tax implications.

@Forest WuRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

The official source I was able to use is the National Association of Realtors site and it shows Multi-family market cap rate of 6.1% for 2024 Q1 (2023 Q4 was 5.7%).

What options are available for a lot that is no longer buildable?

Lastly, when i try and call them to speak to my property manager 99% of the time I wind up having to submit a note in their portal and wait for a call back.As to to the new garage door that will be installed by the tenant, I wish they would be more involved, giving the tenant some options of companies to call, and to walk them through the repair process.Am i wrong in any of these thoughts or concerns about my current PM---or---do i need to let the property manager do their thing and learn to take a step back?

Some states have source of income protections that would not allow you to decline an applicant solely based off of their participation in section 8.

What cost-effective options are out there? 

Could that be an option?
