There are a few parts of your question missing, first of all is it a multifamily, office,retail,etc. Also is it owner occupied,you mention a business worth $850,000?
What is the cap rate? What is the value of the property?
For the purposes of this answer we will assume their are no ltv issues or cash flow issues and that you have an owner occupied multifamily property. For loans below $750k there is a slight upward price adjustment.
For owner occupied-where you live in one of the units, the rates are in the mid to low 4’s,if you do not occupy a unit it is closer to 5%, this is with no discount points. This is for 5 year fixed rates as you asked for in your question.
If you have more questions or if I am off in any of my assumptions from the missing data,please let me know.
