I did most of the cold calling myself at first, then we trained an in person caller so I could supervise a bit. 

Everybody is money driven in this business.When a buyer's agent sees 3.5% or 4% showing up in the MLS Broker Synopsis, you can bet your bottom dollar they will make every reason in the book to show that property.It doesn't matter if it's a meth lab or a crack house, buyer's agents will come out of the woodwork trying to grab that 4% Commission!

I'm a member.Furthermore, I can dedicate full time to this and be on the job working and directly supervising all the crews.

Moving to the Florida Keys, Marathon in specific.Looking at meeting other investors in the middle keys.We (wife & I) are a team of 2.5 (including our chocolate lab), with intentions of buying and holding long term rentals.

So I have quit my job as a Lab Tech and dove head first into this real estate thing.

I have seen it in other posts if I'm not mistaken that 10% of their rehab cost is the usual when you have a manager to help you hire the contractors and Supervise and to make sure everybody is doing their job.

Also, I will supervise the rehab of the apartment building so that we can get the units filled again. 

But for most unskilled work, they need supervision. 

This would be beneficial to us, as we could have somebody supervising the job dedicating more time to the research of new deals and we would like to establish a long term relationship, but so far we have been asked crazy prices compared to the others we get from separate estimations.

If they are not an Associate Broker or a Broker, you must obtain written confirmation from their Broker that they will supervise the real-estate salesperson.
