This is a good question since I do not want to commit mortgage fraud - my plan was to list it for rent around 90-120 day mark and file a work relocation letter with my issuer letting them know my employment situation has changed to a new location.

Most of my landlords & seller-clients are facing a similar situation: does it even make sense to refi or sell the property? 

I'm sure there will be one person with a perfect scenario including an unreasonably low LTV that will disagree, but I don't believe your asking for what is the lowest they can go in a perfect situation, but rather what is a realistic rate you can expect in the future and 7% is a realistic low end. 

I seem to be leaning to Penn Mutual, but I see they do not have a sales department; rather, I must first find a financial representative to perform the contract. 

At the end of the day, it is really dependent on your situation.

Has anyone found themselves in this situation before?

I'm in an unusual situation where my buddy who happens to be a GC put up 100% funds to buy a flip, and I'm doing the realtor legwork. 

We have had so many situations with people trying to sell vacant land they don't own, that our MLS put out a warning about it for all agents. 

Additionally, the retail sector continues to reel under the pressure of an accelerated shift to online shopping, further exacerbated by the economic repercussions of global challenges.Moreover, the financing landscape has tightened, with rising interest rates putting additional pressure on property owners struggling to meet their financial obligations.

I think you are in a really good situation if you can find a way to make it work, given that low interest rate and what people in this thread are saying is a hot market.
