Yes, rental properties that are within walking distance to train stations can be more valuable than similar properties that are not. This is because easy access to public transportation is a desirable feature for many renters, particularly those who commute to work or school.
In your case, the new train station and the development of lofts in the area suggest that there is likely to be growing demand for rental properties in the neighborhood. However, it's important to remember that the overall quality of the neighborhood and the school system can also impact the value and appeal of your property to potential renters.
As with any investment, it's important to conduct thorough research and analysis before making a decision. Consider factors such as rental rates in the area, vacancy rates, and any potential costs for renovations or repairs. Additionally, consult with a real estate professional or financial advisor who can provide more personalized advice based on your individual circumstances and goals.
