That's a great question Yes, you can buy an investment property post-bankruptcy and even after other challenges such as foreclosure, liens, judgements and collections. I work with many lenders who finance investment properties including 1-4 family, mixed use and commercial buildings who have loan options for a business owner in your situation.
You mentioned that your BK is over 2 years old and that you have very good credit now, and a successful day care business in the property you want to buy. You will also need to show enough assets to cover a minimum down payment of 25% of the purchase price, closing costs and reserves. You do not need tax returns for many investor mortgages.
Send me a message if you'd like more info. All the best.
