What is the main action Charlene takes with her properties each year?

The choice indicating that Charlene buys a new property to fix up captures her proactive approach to real estate investment. This action reflects an entrepreneurial spirit, as it involves seeking new opportunities for property enhancement and value creation. By purchasing a new property each year, Charlene is likely focused on expanding her portfolio, renovating distressed properties, and potentially increasing her revenue through subsequent sales or higher rental income after improvements.

Investing in fixer-uppers can also signify a commitment to revitalizing neighborhoods, improving property conditions, and contributing to local housing markets. This aligns with common practices among successful real estate investors who leverage renovation projects to maximize returns on investment.

The other choices do not encapsulate this proactive investment strategy as well. For instance, simply managing existing properties reflects a more passive approach, whereas increasing rent focuses on existing tenants rather than expanding one's property portfolio. Selling a property, while part of a real estate strategy, does not illustrate the commitment to improvement and growth indicated by purchasing new properties. Overall, making regular acquisitions to renovate enhances both Charlene's business prospects and her overall impact in the real estate market.
