Expect the housing inventory to be much older then in Columbus. Most of the investors new to the market are surprised when they see properties that were built in 1890's.
Traditionally it's been Eastside for appreciation and Westside (West of 75) for cashflow.
C-class neighborhoods can be very street by street which makes it more difficult for investors.
These would be my top strategies ranked for the market:
1. Healthcare focused- Major healthcare operations and healthcare developments
2. Student rentals- Two major universities within 5 miles of each other
3. Value Add- Plenty of older housing inventory to fix-up
4. BRRRR- Combination of smaller properties with plenty of rental demand
5. Fixed Income- Just like the rest of Ohio, plenty of fixed income residents who need proximity to healthcare, public transportation, and other urban amenities.
Honorable Mention:
Short Term Rentals- Would be limited to downtown or NKY but all year round demand and limited hotel room inventory
Let me know if you want me to send you a market presentation I recently did for an out of state investment group.
