We sand down all our cabinets prior to painting.

Everything Paige said and a few more.All vehicles must be licensed, tabbed and operableNo water beds, pools, portable heaters, portable dishwashers, portable clothes washers or dryers shall be used on the premises without prior written consent of agent/owner.No dust, sand, dirt, rubbish, coffee grounds, feminine products or other foreign material shall be flushed or washed down toilets,sinks, or wash basins.

Thankfully you have partial overlay cabinets, so some wood-fill for the holes, sand and touchup paint.Not sure what is on the other side, or over, your range, but me, adjusting the layout would be the ideal option, but will likely not be cheap, since it will almost certainly result in new counters, if not also some fill and/or a new cabinet or two (depending on if any cabinet to the left of range is able to be moved over to corner area).What was originally there?  

I've seen some beautiful outdoor paths & patios done this way etc, fill in the gaps with sand or concrete.You might also donate it to a habitat for humanity store (call and ask if they'll take it first) where they might get it in front of the right set of eyes. they might give you a tax donation receipt?

I checked, my sand filter system is about $55k to put in a new one.

The subject property you listed is in a solid location, its close to both Short and Long Sands Beach (two beaches in the area). 

Built and installed the cabinets, trim work, sanding the stairs, drywall repair/patches, demo, pressure washing, installing new doors, fixtures, etc..

On the other hand, in the coastal markets of NC (at least where I have experience), there are little regulations but increasing saturation in the market. 

So, IMHO, if you really really want to use Fix-It-All outside, the approach you mentioned sounds reasonable: prime the wood first, patch with Fix-It-All, sand and then prime and paint.

Today it is worth about 350k, which comes out to about 4.5% per year and that includes the 1970's, 80-'s and 90's - basically 3 decades of economic decay in Milwaukee.
