Hey @Emily Peters, I also live and invest in the Charleston area and I don't see things cooling significantly for buyers in the next 12 months.
But I agree with Jon that house hacking is the best way to get started. The property I bought when I moved to Charleston was a duplex in Park Circle that I house hacked with a 3.5% down FHA loan. At the time, I didn't really feel like I was getting a "deal" on it and the market was still very competitive. For 2 years the income from the other side covered the majority of my mortgage, and after we moved out we turned our unit into an Airbnb and it has been performing extremely well. It has also appreciated significantly and allowed me to pull a HELOC on the property to use for other opportunities. It has put me in a great position in just a few years, and at the time I felt like I was overpaying for it and almost didn't buy it which seems crazy to me now.
In the Charleston market today, it's rare that your first deal will be a homerun in Year 1. But if you hold onto the property, its year 3,4,5, and beyond is where you will see the benefits. I would just make sure it cashflows as a pure long term rental (non owner occupied) so then you have options after you buy it. There are still some solid house hacking options in Charleston, and with some great owner occupied loans you can get into these properties for fairly low money out of pocket.
If you have any other questions about anything feel free to message me, happy to help!
