As a new investor, you need to possess encyclopedic knowledge of your market and that means living and breathing it.

I would set a date 10 days out after possession of a condition sheet checklist and do a walk thru of each apartment, give them copy and this is what you base your security damage repairs on, from that date.

Buyer will be responsible for the possession of the property upon closing.

But I have used a CFO (Contract for Option to Purchase) for many years.I wrote about the CFO here http://www.biggerpockets.com/blogs/3/blog_posts/25788-cfo-and-a-leaseRE: The CFO - The key to this is you use - a lease and - a contract for option to purchaseIt is a landlord tenant relationship with the leaseYou have to finish the lease as a condition for the CFO.The Option is drawn ahead of time and held in escrow for the buyer, and the buyer has a short time to get the mortgage.The Option is not in the possession of the end buyer until the lease is finished (addresses the equitable interest issue).Conclusion:If you are Licensed in California:Do not close LO assignments on the kitchen table with no witnesses or notary.Realize that the courts will always side with the inexperienced Seller or TBer and not you the REIDo close these in the Attorney's office in California with all the disclosures and releases of liability.There are alot of lawsuits in California.

@Derrick Moore I have that in my possession.

Notice to quit(1) A tenancy may be terminated by notice in writing, served not less than the respective period fixed before the end of the applicable tenancy, as follows: (a) A tenancy for one year or longer, ninety-one days;(b) A tenancy of six months or longer but less than a year, twenty-eight days;(c) A tenancy of one month or longer but less than six months, twenty-one days;(d) A tenancy of one week or longer but less than one month, or a tenancy at will, three days;(e) A tenancy for less than one week, one day.(2) Such notice shall describe the property and the particular time when the tenancy will terminate and shall be signed by the landlord or tenant, the party giving such notice or his agent or attorney.(3) Any person in possession of real property with the assent of the owner is presumed to be a tenant at will until the contrary is shown.(4) No notice to quit shall be necessary from or to a tenant whose term is, by agreement, to end at a time certain.(5) Except as otherwise provided in section 38-33-112, C.R.S., the provisions of subsections (1) and (4) of this section shall not apply to the termination of a residential tenancy during the ninety-day period provided for in said section.Based on this, it looks like for month to month occupants, 21 day notice is the appropriate time for Colorado, but I wasn't sure if there was any specific code that needed to be followed in Arvada aside from the Colorado text above.  

Information is Power – get as much as you can.Ask questions, what is the reserve (sometimes they will tell you, sometimes they won't, what is the balance of the mortgage, if you are the high bidder will you get the property free and clear of any liens – can you have immediately possession?

Then you can take possession of the property once all the redemption rules are met.  

Let me clarify...I assume the home is still in the foreclosure process since the bank has not taken possession of it yet or listed it with a realtor.  

I believe your marketing must reflect how the specialized knowledge that you possess can/will solve your prospects problem(s), primarily through using your expertise to build trust.
