Best way is to do your (1) do your homework, and (2) show how it can increase NOI. Don't just say it can, show in real numbers how something can make a difference in the cash flow. As an example, I teach a principle called "CBA," or Cost Benefit Analysis. Sometimes asking a question you already know the answer to can get you what you want. "Mr or Mrs Owner, if I can find a way to improve NOI and get you an income return over expense that is 6 to 1, will you consider it?" I had an owner one time that did not like to spend money, even when it could increase income. Only if you could show him the result and had strong analysis to back it up did you get what you wanted. We wanted to expand marketing and add a national advertising Internet site. His first questions was, "Is it free?" We called competitive sites within the primary market that were using the source and found they were getting an average of 5-7 leases per month from this site. Their occupancy was about 3% higher, and we had very similar product and our closing was about the same. The numbers we presented were from our comps, including closing and the leases from marketing mediums. The primary difference in 4 of the 5 competitors was the increased traffic and leases from this internet site. At an average of $800 per month, per lease, this provided for an average of $4,800 per month or $57,600 per year in increased revenue. Cost per month was $325 per month, or $3,900 per year with an NOI expected improvement of $53,700. Divide that by a 6% cap rate and you get a property value improvement of $895,000. Now you have their attention. We not only made the estimate but increased occupancy and from that point on had an easier time in getting what we asked for...especially at budget time. Good luck.
