That would not only void your opportunity to actually do a 1031, it would also create an immediate taxable event.Certainly a refinance where you pull cash out is no problem. 

Or should I try to find a pool of investors large enough to get the next property and create a new LLC each time? 

I don't think it is a problem asking a real estate broker for the cap rate in an area, just be aware that they may not truly know the answer (in other words, do your own research as well).

Have my monthly schedule for the rentals run from 15th to 15th (I see several advantages to this, but the fact that it would be out of sync with most landlords might create significant problems).3.

If you can afford to create a unit, how about: buy a different value-adding proposition?

Are there any other disclosures or forums I need them to sign or be aware of?

The same enrolled agent also suggests that opening a 'property management' business should allow the deduction of the overhead 'cleanly', but frankly creating a Sch C business with only overhead expenses to support Sch E activities seems to be 1) a HUGE RED FLAG as there is NO INCOME to the business created, and only expenses incurred over SCH E activities only.

the turn key marketers  ( just think as real estate brokers nothing more nothing less)  their clients are the guys and gals that live in the market buy the homes that need rehab and then resell.. they are flippers.. then many will have in house management which makes them " turnkey "  the real risk as Ivan is talking about is buying low end C class.. for most out of state investors over time the expense's create an investment that maybe you would not have made... where as A and B class tend to run fine in any city you buy them in or anyone you buy them from... you can go right on MLS and buy them.. 

I am prepared for the work as I have started my own business I am very much aware that it does take energy and effort and it will not build itself.

Also, you not spending all the money on the repair does not create income for you.
