The Bottom Line

HoldMercer is a neutral market. Consider house hacking or targeting below-market deals.

Mercer County in New Jersey scores 54/100, ranking #0 of 0 US counties (top 50%). At 20% down and current rates, a median-priced rental loses about $640/month; the 7.00% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
