As in, can you still get the favorable owner-occupied loan/terms if a small multifamily unit also contains a retail location on the ground floor?

It's overall bad news for those would-be buyers who hoped that COVID would present them a more favorable market. 

Spell out this is top dollar along with the lookers traipsing through their house, (COVID paranoia is in your favor here) and lenders requiring repairs.#2 What a landlord might offer.

Be warned that you are now speculating (educated gambling), and a gentrifying neighborhood can quickly fall out of favor. 

We are coming from heavy rent-controlled jurisdictions, which I am assuming in TN is much more open to favorable landlord/tenant relationships without all the rules?

We knew we had great equity in this house and when we moved out, we put it on the market to sell or rent because both avenues showed favorable projections.

Number one most favorable thing.

(Which changes your legal contract and should be allowed.) pick terms in your favor, such as an extra move out fee, and that they will continue to pay the prorated rent weekly until the unit has new tenants moved in.

A judge will probably not rule in your favor if the contract is not fair.

Leverage your money, especially with favorable lender terms, and use the rest to invest in further units/properties.
