I am a bit weary of those older buildings though, since the collapse earlier this year. 

The revenue collapse data doesn’t ring true for me.

@Joe Villeneuve  The loans at 75% ARV I submit to you are more than the properties are worth if you were to have to sell them NOW on the open market through the MLS ( not through a TK company or your marketing efforts) What an investor who is not you would have to do to sell them... this is why the mortgage market collapse and why you still have short sales mortgages are higher than the true value..

Let me just sidestep on that again I had a client who wanted to buy a house for around 600 grand and I said don't do it you're on the high side of the market the market's gonna collapse he said well my wife really wants his home she loves it and we have all these reasons why we think it's going to make all this money which is very common for people to believe.Because they believe that in the market it's going to make a lot of sense and they have this great plan that they're going to see go through and make it right and so you can't convince them otherwise they're emotionally tied to this home it's the one they've looked at wanted all their life those types of arguments or scenarios.What I did is I said well if you're going to buy the asset or the home in the attic said there was a potential that the person would own or carry that's really where you'd want to go with that.

I always scope the sewer line if connected to city sewer 10-15k if collapsed or broken.

I like Sub S corps much better than LLcs for flips, be able to collapse the Corp after the deal is done. 

We shouldn't prey on the economy to collapse because it has unforeseen consequences.

Top end homes in Vancouver have collapsed but the rest of the product is still priced high.

The adjustables are hollow and will collapse much sooner in a house fire.

If the house had water damage and it caused the roof to collapse, walk away.
