@Angeline Mentor I've done this many times. The non-QM (qualified mortgage) programs are all different so you need to ask a lot of up front questions. One lender refinanced to my LLC with a personal guarantee but still reports to my credit (Impac Mortgage) which I have taken up with the bureaus. I just closed 2 refinances with RCN Capital and after getting a better understanding of how they price loans I felt that was a good process. A new thing experienced with RCN was that they want a full Alta title policy with extra endorsements which added about $1000 to my closing costs over the regular policy most lenders use. Not a big deal, but a surprise nonetheless.
I currently am in a stalled refi with Finance of America because they are requiring that I take out a commercial insurance policy so they can be listed as "additional insured." Again, never thought to ask this question up front because it's the first it has ever come up, and now I have paid for an appraisal and had my credit run. The additional cost of the policy negates the competitive interest rate so I'm going back through my lender list.
Others that I have spoken with, but not exhaustive because there are a lot who do not lend in California where I am, are Lending One, Lima Capital, Visio, and 5arch. I also looked at a blanket through Corevest but didn't like the idea of having to create yet another single purpose LLC and move the properties into it. PM me if you have any questions.
