Make this easy on yourself and hire a property manager.

I don't reward thieves by handing them more money, but that may be the right answer for you since you aren't sure how to move forward.In the future, you should consider hiring a professional property manager.

I hired roichamps dot com to do cold calling for me.

What is the benefit to the land owner to giving you equity versus just hiring another design/build firm and paying them for their contracting services without giving up equity?

So good hiring/firing ability for office staff and contractors or people management skills if you want to call it that. 

You could also hire a mentor to help you out on your first syndication. 

I will hire it done in the next house I buy.

One thing we are doing now is we hired someone to do monthly walk throughs of our properties to make sure everything is in order (not just with the cleaners, but also the TV remotes having batteries, the pool table having chalk etc).

Let them know despite repeated attempts to collect the money, it is not forthcoming and that you will be starting the eviction process for non-payment of rent...then hire an attorney who specializes in evictions and get the process started.

@Bagus Adiyantoif you're not already working with an attorney i'd hire an attorney to advise youhappy to PM you a recommendation
