Hey @Spencer Lindquester, I see a few property management platforms suggested.

I believe the platform manages all of the concierge services.I'll look into it a bit more but wanted to see if anyone here had any insight or properties on the site. 

If you are looking for a full-time property manager I'd highly recommend @Matt Maurice or if you looking to self manage you should definitely check out the cool platform under my signature - NestEgg.Also, I saw @Kenneth Garrett mentioned @Joe Mueller, who you should also connect with. 

I threw my property up on the platform and within a week was booked solid for nearly 3 months.

@Karen Higgins I built my system using Podio as a platform.

an online platform isn't going to do it and a realtor isn't going to do it either without being way over priced and overrated.   

Don't worry about the 'brand' name, it's just a platform to operate on, no different than Realtors.... the Keller Williams or Long and Foster is irrelevant, what matters is that Realtor.

We're speaking with the neighbors to see if they would be interested in selling so we can expand our project, but we know the number of units each parcel add to the project, and what the max acquisition cost will if we were to buy them out.You should be able to pull up the sale data of the property from a platform like Zillow to see what they paid for the land, and gauge where you want to come in for your negotiation. 

First you need to confirm if you'll qualify on crowdfunding platforms.

@Gustavo Carbonero The BP platform is great and will help you.
