If it was **my** home, I have no problem with going with an off the shelf Home Depot window - but I've found that those tend to be smaller than the opening allows (because you have to buy off the shelf, not custom) and if you do go custom with Home Depot, it's more expensive than Window World.So while doing the windows for my own first home was acceptable, now I tend to just hire Window World when I need windows. 

However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

I wash them up and get them as clean as I can and put them on the lower shelf of the master bath linen closet as spares guests can use for a kid that needs cleaned up.

I think if you built decent homes, in the 325-350k range, 4 bed/2 bath, 2500 sq ft or so, they would fly off the shelf.

If those windows are original they are made from "old growth" wood and you just don't buy them "off the shelf" anymore.

I used his firm to do a 1031 exchange three years ago - excellent support and infinite patience with my endless questions.

Then, as long as it cash flows, your return is INFINITE, since you have none of your own money left in the deal. 

Because the lot is narrow and long (50' x 200'), the typical off-the-shelf plans won't work (we want to do custom anyway), so my partner and I have been discussing ideas and he's been putting some sketches on paper.Here is what we plan to start with when we find our architect (click to enlarge):We've been debating whether the second floor (the drawing on the left) should be the full size as the first floor, or whether we should gable the roof to limit the size (as in the drawing) to keep the square footage to our planned 2000 sf.Making the second floor the same size as the first will add some framing, sheetrock, paint and finishing cost, but will likely also add about 700 sf to the footprint.

So it’s infinite cashflow from here out.

Number one reason is, you will still be liable to asset exposure if you don’t protect it correctly, a shelf corporate filing is not enough and maintenance of an llc and corporation is always an upkeep.
