What this tells us about Portage Park
At the Portage Park median, a typical BRRRR project produces approximately $-489 per month in cash flow after a 75% LTV DSCR refinance. With approximately $70K remaining in the deal after refinance, this represents a -8% cash-on-cash return on the remaining capital — before appreciation.
Portage Park is one of the most consistent bungalow flip markets in the city. The dormer-addition play (converting attic space to add a 4th bedroom) lifts ARVs reliably by $50-75K when done well. End buyers are primarily owner-occupants.
How this scales across Portage Park
Portage Park's housing stock includes Chicago bungalow, Georgian, 2-flat. Multi-unit properties (2-flat, 3-flat) typically produce 30–60% higher gross rent than single-family at similar ARVs but carry higher tax burdens and management overhead. Single-family rehabs often have stronger exit liquidity (owner-occupant buyers) but lower cash flow.
Sensitivity considerations
- Rent assumption: Modeled at ~0.85% of ARV. Actual rents in Portage Park range from 0.6–1.0% depending on property type and condition.
- Property tax: Modeled at 2.5% of ARV for Cook County investor classification. Successful tax appeal can reduce this 15–30%.
- Interest rate: DSCR refi rates currently range 7.5–9.5% depending on borrower profile and leverage. A 1% rate change moves monthly cash flow by approximately $100–200 on this deal size.
- Rehab budget: Modeled at midpoint of $45K–$135K. Common considerations on Portage Park housing stock (original windows, aging mechanicals) can push budgets higher.
