Anne Arundel County

Anne Arundel County sits at a gross rent-to-price ratio of 0.056, which translates to a 3.63% cap rate on a median-priced asset at $502,145. That's well below the threshold most cash-flow buyers require, and the model confirms it: at 6.85% financing with 20% down, you're looking at negative $1,113 per month in cash flow and a cash-on-cash return of -11.56%. The affordability index of 28 tells the same story from the demand side, meaning renters are stretched relative to incomes in this market. Year-over-year home price appreciation of 0.86% is barely above flat, so the market isn't compensating with price momentum either. On the cash-flow-versus-appreciation spectrum, Anne Arundel lands in neither column convincingly, scoring 54 on cash flow and 59 on appreciation, both middling figures that reflect a market priced for a different rate environment than today's.

The investor profile this market suits is narrow. A leveraged cash-flow buyer gets hurt immediately: the numbers above show that clearly, and there's no creative financing that makes a -11.56% cash-on-cash work at scale. An appreciation buyer has a slightly better case, given the 59 appreciation score, but 0.86% trailing price growth is not a compelling near-term story. The most defensible position is a long-horizon buyer who expects the DC-Baltimore corridor to continue attracting high-income professionals and is willing to carry a negative position for several years while equity builds, or someone targeting value-add assets priced meaningfully below the $502,145 median where the rent-to-price math starts to improve. A value-add operator who can force appreciation and push rents above the $2,337 median will get to breakeven faster than one who buys at market.

Anne Arundel's rental demand story is tied structurally to its geography, sitting between Baltimore and the DC suburbs with Annapolis as the county seat and a significant presence of federal government activity through installations like the Naval Academy and proximity to NSA and other defense and intelligence operations in the broader corridor. That institutional employment base provides a degree of renter stability that isn't captured in the cap rate, but investors should not confuse stability with yield. High-wage tenants in this county often have the income to own, which is part of why the affordability index is as suppressed as it is and why the rental pool skews toward renters who choose to rent rather than those who have no alternative. That's a quality tenant base, but it also means you're competing with homeownership on every lease renewal.

The combined monthly tax and insurance burden here runs $544 on the median asset, using Maryland's state-average effective property tax rate of 1.09% and an insurance rate of 0.21%. Note that the 1.09% figure is a state-average estimate from Tax Foundation 2024 data, and actual Anne Arundel county and municipal rates may vary. At "normal" by flag, this rate doesn't create the same drag you'd see in New Jersey or Illinois, but $544 per month is still a real line item in a market where you're already cash-flow negative before you account for vacancy, maintenance, or capital expenditure. The $818 in estimated monthly expenses already factors in tax and insurance, and the outcome is still -$1,113 per month. There's no version of this underwrite where the carry costs are incidental.

The most concrete risk in Anne Arundel is concentration. Much of the county's stability thesis leans on continued federal spending and defense-adjacent employment. A sustained reduction in federal headcount or base realignment would pressure rental demand more here than in a more diversified metro. Maryland also carries regulatory exposure at the state level for landlords, including rent notice requirements and eviction process timelines that are not investor-favorable, which isn't a dealbreaker but is an operating reality to price in. The affordability index of 28 is also worth flagging as a risk: if wages don't grow to support current rent levels, there's limited upward pressure on rents, and any softening in the labor market shows up quickly in a market where tenants are already stretched.

Compared to its neighbors, Anne Arundel is not the obvious choice on either end of the spectrum. Talbot County comes in at a rent-to-price ratio of 0.0582 versus Anne Arundel's 0.0559 on a lower median price of $481,463, meaning slightly better yield at lower entry cost, though with a much smaller renter pool. Howard County at $617,631 median and a 0.0434 rent-to-price ratio is worse on cash flow and priced higher, making it a harder underwrite for the same strategy. Montgomery County is similarly expensive at $603,381 with a 0.0456 ratio. Carroll County, scoring 53 overall, offers a 0.044 rent-to-price ratio but at $481,105 median, which doesn't improve the cash-flow picture relative to Anne Arundel. The clearest reason to choose Anne Arundel over these neighbors is institutional employment density and the liquidity of the Annapolis market for exits, not current yield. If yield is your primary filter, none of these Maryland counties solve the problem at current prices and rates, but Anne Arundel at least offers a larger, more liquid market than Talbot and more defense-sector stability than Carroll.
