Can you build a 500 square foot coffee/ice cream drive through.  

That allows you to shave that 10-30% without simply lowering your rates as a whole. 

For the average investor though these HFTs shave a penny or a penny there.

I agree with @Michael S. Having

TL;DR  Lower the price, find more potential buyers (CREAM on FB, etc.). 

Forget the article.Want a toasted bagel with veggie cream cheese for breakfast.Matzo ball soup and a pastrami sandwich for lunch.Walk down the street and let my nose lead me to a great Indian restaurant for dinner.Catch the sub and jump off for a Yankees game.Real Estate Investments:   We do Self Storage, Country Subdivision Lots, Teak Plantation land in Belize, would like to do Flex Contractor buildings.Rising interest rates:1.  

While their data is not 100% accurate (my research has been about 90% in comparison against my actual data) it will shave hours, even days off of your hunt for "where to invest". 

So there is not a lot of opportunity to shave costs there.When it comes to a realtor there's certainly the opportunity negotiate commissions. 

For simple math, my interest payments are about $1300 per month so if I can shave 3 months off of the back end of my estimation on the loan I will actually be able to reduce my costs by about $500 after the sale of the property.

And in an ideal world, those that don’t rent well, will get off Airbnb in the next year or two and the cream will rise to the top.
