Based on your property’s details—1,448 sqft, 3 beds, 2 baths, single-family home in North Charleston—and current comps, the estimated rent potential is $950–$1,375/month, which aligns closely with Zillow’s city-wide average of $975 and Apartments.com’s $1,003 for 3-bed units[1][3]. The Charleston rental market is currently described as 'warm,' with a healthy supply of 55 available rentals and rents up 6–13% year-over-year, reflecting steady demand[1][3]. The property’s large lot (0.37 acres), detached garage, and 2-story layout are strong differentiators for families, but the lack of modern updates and potential deferred maintenance—evident from the auction listing—could limit upside without investment. Flood, heat, and fire risk scores are notable, and insurance costs could be higher than average. The payback period, assuming a $29K purchase price and $1,150/month average rent, is roughly 25 months—impressive, but that’s before factoring in rehab, insurance, and vacancy. Nearby comps show a wide range, but most 3-bed homes in this area rent for $900–$1,400, so your range is realistic.

To maximize rent and appeal, I’d prioritize curb appeal, modernize the kitchen and baths, and ensure all mechanicals are up to date—these upgrades typically yield the best ROI in this market. Consider adding a fence for privacy and pet-friendliness, a big draw for families. If selling, highlight the large lot, garage, and proximity to schools. Market it as a 'value-add' opportunity for investors or a move-in-ready home for first-time buyers—but be upfront about the need for updates. If holding, screen tenants carefully and budget for higher insurance due to climate risks. Personally, I’ve seen homes like this in North Charleston lease quickly when priced right, but they do require hands-on management.
