If she sells the property before that date, she would not qualify for the full exclusion unless she meets certain exceptions such as unforeseen circumstances like job loss, health issues, or other qualifying reasons outlined in IRS Publication 523.Regarding prorating the exclusion, unfortunately, there's no provision in the tax code for prorating the exclusion based on partial years of ownership or residence.

Thank you for the suggestion.

Hope it can become my full time job as I’m done with excel lol. 

I say this as no disrespect to the people in the trades - their jobs can be tough... only as a note to the risks of doing such work. 

I want to be there for them without worrying about 9-5 JOB. 

Could you please suggest me some insurance provider who covers rental property. 

I'm sure that's why your brokerage is suggesting it.

Now the tenant will not leave, and we have started the eviction process.This is a clear (and costly) learning experience for me, but does anyone have suggestions about what I can do to fix this situation?

@Natasha Norregaard, I used Truth Lending as well that @Karl McGarvey suggested.

Also, if you do a great job placing tenants, then your maybe your real vacancy will be closer to 0.
