A single-family property may have additional income potential, but converting it into a legal multifamily setup requires more than estimating new rent.
In one recent homeowner case study, the projected improvement was approximately $16,000 to $17,000 in additional annual net income.
Before moving forward, owners should evaluate zoning approval, one-time improvement costs, egress and code requirements, utilities, insurance, lawn and snow care, parking, tenant disputes, noise, taxes, and turnover.
We use RentRange software and other analysis tools to compare the projected income with the added costs, responsibilities, and risks. We also look at the opportunity from both property management and real estate sales perspectives.
We’ll place the PMI Mystic website and the video link in the first comment. If you own a rental property in Mystic, Stonington, Groton, or nearby, a careful analysis can help you make a more informed decision.
