Prorated rent requirements

[John Nisewonger]

So renting out my single family again and I have a couple qualified applicants.  Just coming across some things that I havent had to deal with yet.  My previous tenants moved in the first of the month.

So I charge $925/mo and $925 security deposit but one applicant wants to move in the 21st.  Do I prorate those last few days plus charge the $1850 move in?  I dont want to just charge those few days prorated plus security deposit just to have to go over there 9 days later to get 1st months rent.  Or is that how you guys usually do it?

What if a tenant wants to move stuff in earlier?  I was going to get a signed lease and security deposit minimum for him to start moving in boxes.  That tenant wants to be living there by the 1st but wants to start moving in a week or 2 earlier.
