We greatly need to increase our cash flow and would appreciate suggestions from seasoned investors on how to accomplish that.  

E-myth and Accounting books are next...Any advice or suggestions are appreciated.   

Suggestions?

What I'm suggesting is: Ask them that - and mean it!

Suggest you review your contracts with a lawyer.

I am going to stop short of actually giving you a suggestion because I am not well versed enough to know what to do in certain circumstances.

Does anyone have suggestions or rental records of similar places in KWGC? 

He would probably suggest using a form of Quickbooks.

YOU still have to give proper notice,, NO way can you do this the way your thinking,,Download your state landlord tenant laws so you can operate this business properly,Get a copy of their current lease,, IS there a clause that says,, it will automatically revert to a month to month term if not renewed for a longer period..IF so your fine,, you'll just give them notice of lease terms changes the next month,, they don't need to vacate if you want to keep them,, you can give them a heads up what the terms will be, you can suggest it would be nice to start off with a new lease, but understand they have a month to accept that new lease or give proper notice to vacate..It's not that it can't be done,, it has to be done the proper way..

I suggest you review the terms and conditions you agreed to before placing a bid.
