There was a Korean family considering whether to buy a small duplex in Newark to rent out or keep their money in the bank while continuing to rent. Since the location allows for commuting to Philadelphia, listings are consistently available, but it was difficult to determine if buying was a good decision just by looking at the sale price.

A useful tool in this situation is the price-to-rent ratio. Simply put, this number shows how many times the cost of buying a home is compared to a year's worth of rent. According to Zillow, the average home value in Newark is $367,052, which has increased by 1.2% over the past year (as of July 31, 2026). Rent, based on data from RentCafe in May 2026, averaged $1,703, which is 0.25% lower than a year ago. Calculating these two numbers gives a price-to-rent ratio of 18.0. A ratio between 15 and 20 is often seen as a middle ground where neither buying nor renting is significantly advantageous.

If the term is unfamiliar, think of it this way: the lower this number, the cheaper the home price is compared to rent, making buying relatively more favorable. Conversely, a higher number indicates that renting is more advantageous. With a ratio around 18, as in Newark, it's a point where you need to consider other factors for both investment and personal residence purposes.

Looking at the trends over the past 1-2 years, Newark has seen steady rental demand due to its proximity to the University of Delaware, while home prices have gradually risen, influenced by migration demand from the Philadelphia metropolitan area. The combination of rising home prices and stagnant rents aligns with this background.

From an investment perspective, the key is whether rental income can cover mortgage payments, property taxes, insurance, and maintenance costs. It's also important to factor in that while home prices are rising, rents are mostly stagnant. If purchase prices continue to rise but rental income does not keep pace, the return on investment could actually decrease. When comparing duplexes and single-family homes, a duplex may have a similar purchase price but allows for rental income from one side, which changes the calculations compared to a purely owner-occupied single-family home.

If approaching it as a personal residence, the first step is to compare the monthly rent of $1,703 with the mortgage payment after making a down payment. If you have a substantial down payment, the monthly payment could be similar to or lower than the rent, while a larger loan amount could yield the opposite result. If the intended residence period is short or there's a possibility of moving in the future, the advantages of buying may diminish due to closing costs. Rental properties aimed at students tend to see demand peak by semester, so if investing, minimizing vacancy periods in line with the academic calendar can significantly impact returns. For personal residence, it's also wise to check for noise and parking conditions typical of college areas. Particularly, listing properties in line with the start of the academic semester can help reduce vacancy periods, a point often mentioned among investors.

Newark, being near a university, has a region where school districts and rental demand move together. While you can refer to ratings from GreatSchools or Niche for school district ratings, keep in mind that school district boundaries change frequently, so it's advisable to verify the assigned school for the specific address before purchasing. If coming from another state, it's also good to note that Delaware's property tax and insurance systems may differ from your previous residence. While it's often mentioned that Newark, located in Delaware, has no sales tax, this pertains to overall living costs rather than real estate transactions, so consider it separately from property taxes.

Whether for investment or personal residence, rather than making a conclusion based solely on this number, consider your financial situation and living plans together.
