Charterbank is a good local option. I just refinanced a duplex with them and the rates were very good for investment property. I think you’ll have to go 20% down with Charterbank though. PM me for my contact there if you’d like.
@Zach Falbo what rates are you being quoted. Here are the components of what will determine your final interest rate:
Down payment-15% - known
Type of property-SFD; condo; multi unit 1-4
Occupancy type - investment - known
For the most part lenders all get their money from the same place; so rates should not vary too much from one to another. If it varies, it usually is by a margin of 1/8th to 1/4 difference.
Don’t base your decision on just lowest rate. It’s important, but my recommendation is to find someone that’s competitive and will be a resource for you long term.
