How to structure my business model?

[Joshua D.]

So me and my wife has a house buying company and a rental property business. We have had going on 3 years here soon, originally it was just me and one guy doing most of rehabs and construction stuff. We now have 15 properties, i went to a different model now having contractors do the majority or rehabs and i have handymen,plumber,electrician and hvac guy i can call when i need them. I manage pretty much it all and my wife does the bills and emails and such. To really grow and streamline all this whats the best way to really scale and get very organized?
