Duplex in Dover, NH

[Jakob Mikhitarian]

Duplex sold in 2025 for for mid $500’s 

4 bed unit and 2 bed unit approx 2000 sqft 

Well maintained 

260k/unit and $260sqft 

Renting out the 4 bedroom can really help offset mortgage. The downside is if it becomes vacant, pretty much all income is lost. 

PITI payment and other expenses are about 5k/mo if owner occupying

4 bedroom unit goes for around $2900/mo and if you get a roommate that could be $700/mo. This could reduce owners living expenses to $1400/mo. 

This compares very similarly to the previous duplex analyzed

Brian makes a good point about this being more of a house hack play. At $260/sqft and $260k/unit in Dover, you're at the higher end for NH duplexes, but Dover has strong fundamentals with UNH nearby and steady rental demand.

I'd want to verify that $2,900 rent for the 4-bed is realistic by pulling recent lease comps in that specific neighborhood. Dover rents can vary quite a bit depending on proximity to downtown vs the outskirts. Tools like Rentometer or PropLab can help cross-check rent estimates quickly, or just scan Zillow/Apartments.com for similar active listings.

One thing to consider with the house hack math: your $1,400/month effective cost assumes the 4-bed stays rented consistently and you're getting that roommate. More conservative would be to assume 95% occupancy and maybe $2,700-2,800 on the rent to give yourself cushion. That puts effective cost closer to $1,700-1,800/month which is still solid for NH.

The flip side is if you're comparing this to renting in Dover, a 2-bed apartment would run you $2,000-2,200/month anyway with no equity build. So even with some vacancy, you're likely ahead long term.

Have you analyzed what this looks like as a pure rental down the road? If you move out and rent both units, the numbers would be different. Curious if that exit strategy pencils out too.
