I've seen single families needing cosmetic work in that price range in NJ. I'm looking in PA too and have seen decent properties that may meet your criteria. It'll depend on the specific markets within each state that you want to buy in.
From a financing side, it sounds like you have a good foundation. Being able to deploy 25% down can give you 2 or 3 different financing plays that may make sense for both of you. The interest rates are what they are so I'd put more emphasis on the mortgage payments and your overall deal analysis (down payment, closing costs, rental income, vacancy rate, cap ex, etc).
I didn't start out with a investment advisor so I cannot speak to the pros/cons of that, yet I can say building a team of real estate professionals who have investment properties themselves definitely helps. I would start interviewing realtors and lenders in the markets you're interested while you're in the early stages of planning. If you can have a team of experienced investors at your side throughout the transaction then this may be a more cost effective option than paying for an advisor.
Hope this helps! Message me to chat more about investing in NJ.
