The last few years I've been seeing great results with simply index investing (which I'm still continuing in multiple IRA accounts) so I guess part of the motivation for real estate was to diversify a little bit  (in addition to the REIT holding I have). 

Setting up multiple LLCs can provide you with more protection, simply by adding additional layers that make it harder for someone to get to you, if they sue you.However, it is probably totally unnecessary and, in my opinion, borderline unethical, for an attorney to try and sell you that level of protection when all you are doing is buying a rental property.

The tenant lied to you about the locks change - he/she should not be initiating this because there is a probably an alteration clause in your lease.He/she did not follow the appropriate steps to sublet, again, lying/misleading you.What is the situation between these two?

Did you get any additional security to guarantee repayment? 

In addition if your going to flip houses you need a developers license..  

If you believe you will need additional time to complete the request ask for it stating that you just became aware of the requirement to provide the documents on such and such a date as the agent never informed you previously. 

In addition, you can send out marketing campaigns to your target market.

Seller will pay liens on title as long as no additional repairs are needed.
