Measured first, IRS SOI recorded 14,713 tax-return households moving from Washington, DC to Baltimore, MD in the migration release, with 24,031 exemptions and $1,235,718 thousand in adjusted gross income. IRS flow means tax-return households. It does not identify renters, every mover or future demand. The $83,988.17 of AGI per return describes the filed-return group, not a salary, lease budget or neighborhood destination. The flow establishes a measured corridor, but it cannot establish how many Baltimore rental units those households occupied.
For household housing costs, the principal change is a lower nominal entry point in Baltimore. The Zillow snapshot shows asking rent of $1,936 in Baltimore versus $2,448 in Washington, a destination change of -$512 per month. Zillow home values are $407,614 and $584,684, respectively, with a -$177,070 difference. Those figures describe market-level asking rent and home value, not the quote a particular household will receive or the condition and location of comparable homes.
The offset is income: the separate ACS release places Baltimore median household income at $99,470, compared with $126,684 in Washington. For rental-property screening, Baltimore’s gross-yield measure is 5.7% versus 5.02% in Washington. That favors Baltimore on gross income relative to home value, but it is not a net return and does not resolve operating or financing risk. The next underwriting question is: at the actual Baltimore property and financing terms, do achievable unit rent, vacancy, taxes, insurance, maintenance and management preserve the apparent gross-income advantage after operating costs?
