But very nice and on the surface, you would never know.

The reason I say spend the time to do this is a deal may look great on the surface but there's often an undercurrent of unforeseen that could topple your cash flow in one fatal swoop for a property the size of what you're looking to invest.

Countertops go solid surface, not talking crazy marble or granite, checkout Wilsonart or Corian.

This is technically a price increase, but on the surface the price appeared the same. 

I just looked at an REO today and there was mold in every room, on nearly every wall and most other surfaces.

Surfaces that come in contact with food or touch surfaces should be sanitized at a minimum. 

Also, if you used a single shim, swap it out for 2 'opposing' that make the support surface flat.

Surface- Rock or hard surface (concrete/asphalt);If on rock/asphalt put your tongue leg or stabilizer pads on widerpads to spread the weight out.

Once you've done that work, you can begin to build a relationship with the banks that surface as the best option, prior to making offers.

If you take this route contact Sika, they have lots of products to repair concrete from just surface grouts to injectable grouts to repair deep cracks.
