@Travis Marko There are several skip tracing companies out there.

(you need to differentiate when a Mark Spain type company is running radio ads to attract business for themselves from it actually helping you out)4) Our TEAM or BROKERAGE has sold "X" homes!

You have to make sure that whatever company you choose will maximize your profits. 

From there, I would like to consider a 1031 exchange in the future to acquire more units.My current property management company suggested that they could handle a mid sized apartment building but I would absolutely not consider them for it as I believe they have overextended themselves and communication is lacking.

If your company were to manage the STR in CR how do you deal with matter of safety / home burglaries? 

Most turn key companies do have a West coast based marketing company sell their props.

I look at who the company associated with.These are just my opinion about it.

Its a lot of work but anyway you slice it a management company is going to cost you 10% of gross rents which could easily be 100% of your net profits.

My family also owned a construction company, so I have some experience in handling projects associated with real estate. 

HELOCs are not available because they are residential loans guaranteed by individuals and what you seek is a type of commercial loan or credit line which are available to seasoned companies with proven financial track record.
