I did see an extended vacancy in one of my units at the beginning of the pandemic when everything was shut down (March 2020).

Is 60 days enough notice or should I extend this? 

Even his realtor didn't know you can't get title insurance for these for an extended period of time. 

Most of these programs want to make sure that you are occupying the property for an extended period, and will have increased fees, and stipulations.

For what it's worth, I will extend you my honest opinion.

Two year ballon with option to extend an additional year.

If they're generally good tenants who pay on time and take care of their unit, it may be wiser to introduce gradual increases over an extended period of time.

If the former, it will obviously extend my closing time.

Therefore, I asked the seller to send a notice of termination to the tenant and extended the settlement date to 3/31.

And when we convert an unused space to an ADU, we're creating even more livable space that can either offer affordable housing for renters or be a true accessory dwelling unit so extended family members can live together and save on expenses.
