Cash out after rehab including rehab costs?

[Toben B.]

I paid cash for a property and the bank will only loan me the amount of the sale and not include the cost of the repairs and rehab on the property. 

My understanding is a bank will do a construction loan and then lend based on a percentage of the appraisal. 

I don't need to get more cash than I put in, but I do want to roll my repairs into the loan. 

My bank says I would have to wait six months. Do I need a new banker?

Thanks
