If this were effecting your ability to lease other units, then you have a different situation, but if this is a single family home, or not effecting other tenants in the building, let it ride and count your cash each month.

A minimum of 51% of the entire building square footage is for residential use and the commercial use will not effect the health and safety of the occupants of the residential property. 

I bought this spray which people in the reviews and Q&A said worked to remove stains when other products failed, but this had no effect on the washer rubber gasket stains.

The little steps are part of a large domino effect--wishing you well on the rest of your journey!

You can give them notice as soon as you want, but just make that notice effective on the tenant's move out date. 

I'll leave an example below that I just had, but seeing that many new folks are looking to start out with a househack, I think this is a good place to just dialog about this particular issue.In the most recent example we saw, we found a home with a sizeable lot, somewhere to the effect of being 4-5 lots in size for the average neighborhood in the area, with potential for just a slight cashflow as-is, but as we saw it, the opportunity to expand by building a detached garage with an apartment over-top that would allow us to keep kosher for owner-occupant with the lender, but up the cashflow for the property by a good estimated $600 a month.

The larger the building and more units under one roof the more cost effective the build per sqft.Best way to do cost analysis is to discuss with a builder who builds the types of buildings in your area and run the numbers. 

Or, if you want to ditch the MA LLC altogether, you open the OH LLC, transfer the entity (talk to the lender first though) wait at least a full tax cycle because the MA LLC has to exist in order to pay taxes and effect transfers) and then shut down the MA LLC. 

Please consult a tax professional immediately because this question is really the ira status and what it does or doesn't so and how thst will effect you.

If we did a higher %, say 30%, the opposite effect would likely happen.
