@Kelly A.
As others have mentioned, things get a little more complicated with commercial loans. Fortunately, there's a ton of education out there on CRE debt especially when it comes to programs like Freddie SBL or Fannie Mae Small Loans. As a lender myself, I'm seeing rates in the mid 3's for under $7.5M. There are a ton of interest only options too that could be very attractive depending on your use case.
I'm also seeing a 30 year fixed FHA loan for under 3% still.
Are you leaning towards recourse or non-recourse financing?
Whichever route you choose, make sure to keep your lender honest! Get their underwriting ASAP, make sure their comps are fact-based (e.g. not dependent on the appraisers mood), ensure their expenses are within the reasonable variance of recent transactions, and most importantly keep their delivery timeframes short. They say 24-48 hours, but often it takes 1 week for some junior analyst to give you a quote.
More often than not, by the time you get the term sheet, the property is gone! If only there was a better way!
