Financing an all cash purchase???

[Jacob D. Lange]

I am purchasing a property all cash.  Is there a period of time I would have to wait before I could then secure a mortgage on that property.

I heard 6 months, but that might be only for a re-fi.  

For context, I am buying a property for 65K.  With 8 to 10K of work, it should appraise for 100K or a bit more.  I hope to get a mortgage for 75% of the appraised value.
