One of the aspects that probably contributed to the triples failure is that they are a lot heavier with 3 panes of glass and I suspect that the mechanisms are the same as the 2 paned mechanics and not beefed up for the extra weight.Some earlier replacement windows were aluminum but today most are vinyl. 

Cash flow is just a byproduct of gross income - expenses.

Returns vary by product, and 16% is not much of a stretch but 20%+ requires a bit more creativity. 

Did a 7 hour round trip to Pella, Iowa to get Dutch Pastries at Jaarsma Bakery and some Beef Sticks/Jerky at In't Velds as Xmas gifts for all the Bankers and Contractors. 

It's not just redesigning the roof, it's beefing up lower walls, adding floor joists in the upper floors,  etc. to handle the new loads.

And no extra cost as this activity was included in the price to harvest the logs it was a by product of the logging activities.

But I see plenty of others were the deal dies not sure if the wholesaler stills closes I suspect not.. that's my major beef with these guys is not closing and hurting sellers especially desperate sellers..

I also have a soft spot (pun intended) for BBQ turkey in any traditional BBQ style and for a good bowl of beef Pho. 

At the same time, I would beef up due diligence even if it costs a few thousand more.

Also, one thing I've warned out of towners about buying here when I hear these people raving over our low entry prices and what looks like GREAT cash flow (assuming you get paid your rent) is to figure the city of MKE into your plans BIG TIME and that's double the reason why I'd say to get a much larger reserve, unless you find some new line of credit to tap that's at a LOW % rate, because the city inspectors are usually just fine to work with, BUT the city govt has a big beef with anyone coming here who thinks (and NOT meaning you here!)
