Hello Allison! Congrats on making the first post and welcome!!!
So... Like all business decisions it's all about the Pros and Cons. If I was in your shoes I would ask myself these questions..
What is your end goal? 3..? 4...? 15 Properties? You don't want the final stages of life to feel like a rat race trying to build an empire the last minute.. So, Will NOT selling the house now prevent me from buying a investment property in the future? Could I be maxed on Debt to Income already? Or too close to prevent another purchase?
You stated that your long term goal is to invest in the Grand Rapids area.. Are you content with having a home 3 hours away? What if a pipe breaks? Tenants trash something? Can you find an A+ property management (PM) company to assist if your life gets too busy?
I would try to limit as many risks... If I find an A+ PM company to assist me that is thorough and meets my needs.. then build that equity and set a goal of when you would like to sell. (If your long term goal is to invest in the Grand Rapids area)
Also... lets say 5 years down the road you need to sell that property.. Do you think you can sell it with tenants living there? If not, Can you afford the Mortgage plus your Rent for a few months? (Limit those risks!)
I hope I helped, Good Luck!!!
