Judging from the fact you have someone there 4 months and still haven't filed for eviction you should probably hire an eviction attorney and a property manager.

I have had several Colorado LLCs (single member LLCS with one single family residential rental per LLC, so very small-time) for a decade, and always file my periodic report so am in good standing with the Colorado Secretary of State, but have only just heard that I need to file a BOI report before the end of the year.

File Bankruptcy and fix your house up and sell it or sell it as is for the amount you said it was worth vs what you have it under contract for now.  4.

In my experience, the turnaround time is fairly short and can be done in January/February and still leave enough time for your accountant to file taxes. 

Whether it's mold, COVID, or a non-paying renter, a quality PM acts quickly and decisively to protect people, property, and the landlord.If you feel the PM was negligent in their response, you can file a complaint with the state commission.

If so, your IRA will most likely need to file a 990t tax return annually and pay this tax. 

However, managing multiple LLCs can mean higher costs and administrative work (separate bank accounts, annual filings, etc.).It depends on your risk tolerance and ability to stay organized.

They sent me the Excel files over and I was made to believe it was optional.

A good way to avoid this in this future is to use a vendor worksheet/package that request the pertinent contact information along with a document request for the filed out W-9, copy of business license, Worker comp and liability insurance certificates.

and do you know if they came back to the states.. that will be a HUGE win for anyone who is litigating against them .. at least right up until they file BK.
