If I shared the price people wouldn't believe it so I'll leave it at that. 

I do most of the putting out fires, hiring handyman, bribing people to not leave a bad review because they saw dust on a ceiling fan blade (lol). 

Would you recommend leaving this as is for 2020 taxes?

The best option is to respond quickly and professionally in hopes that they move out.I would give the tenant two options: 1. vacate the rental in one week, leaving it in the same condition as when they moved in, and I will refund their deposit within 72 hours; or2.

But always complaints about guests (residents) leaving common space a mess, some resident gets mad they have to clean up...   

My question is can I purchase this property, renovate the top two units and just leave the basement as is?

Most seller finance notes have interest rates in the 9-10%+ range.Also, 5% down is very little skin in the game for the borrower.

If the call is important, they can leave a message and/or text, and state that in your answering message. 

Are you ok with them leaving and starting with new tenants?

When ADU is complete, rent it or move in and remodel main house.After a few years, I think it is highly likely (again wouldn’t count on it, but would leave the possibility open) that CO allows and encourages those who build ADUs to subdivide their properties so that more people can own their homes.sell the ADU and main house separately, benefit from enormous upside.
