When acquiring a large portfolio of rental properties, what strategies have you found effective for managing or dividing the properties?

If the later, then set a timeline for say 5 years (don't care how long) and then sell and go your separate ways.I do have a business partner/friend on the investment side and we have three properties/ten doors together.

When that is the case if that bill is unpaid it can result in a lien on the property!

I’m a construction manager with years of experience working on rental properties and flipping homes.

Why he even considers selling his property at 50% off? 

I know you are probably bummed about this and feel like you made a mistake, but if you can figure out how to hold this property and buy more properties and hold them then you will end up making significantly more money in the long run; you don't build a real estate portfolio by selling.
