I'm not sure if there is a clear answer to this. The rule of thumb for a clean bulk is something like 500 calorie surplus. It all really depends on your metabolism, your height etc. I've seen guys who can cut at ~2800 calories and are really short, whereas I have to be around 2000, it might be that my metabolism is highly adaptive or damaged to some degree, or that the other guy just has a freakishly high metabolism(likely the latter). I think your fat would first be distributed to wherever your fatcells are, I used to be much bigger and as such when I start 'spilling over' the first places I notice fat accumulation is around my obliques, lower back, lower abs. These are typically the last areas or stubborn fat areas. There really is no clear cut answer especially not knowing your stats, just go 500 over your perceived maintenance. Maintenance calories is a moving target so you'll have to watch your total daily energy expenditure, as well as the weight scale and increase calories accordingly.
