I was wondering what some cost-effective ways of improving a commercial apartment complex might be. I know that I still need to fix some fencing, replace lots of old A/C units and their duct work, make the pool look nice, and repaint the entire place. What would give me the most bang for the buck? Does anyone have any experience with building improvments? Maybe installing new windows? The windows here are about 25-50 years old. Everything else on the interior has been refreshed. There are 30 units here, and I'm looking to make a $200,000 improvment to the value at the minimum, while spending as little as I can.....what are most renters/investors looking for? If I can bring the rents up a great deal then I can also increase the value of the property. It has been slightly neglected, and I can post pictures if needed. Thanks for any advice.
