Eventually in the short term, door knocking yields the best leads, but it's probably not sustainable unless you plan to hire an army of knockers (unless you are one of the few that actually like it)

Quote from @Carlos Ptriawan: We are the only 'asset class owner' so far that doesn't get hit in the last two months.Simply because the government can't print houses.If they can, we will crash too lol, thanks to 2008 stricter lending practice.In the last 60 days:Crypto owner wiped out stock owner is bustedBond also crashedmoney-market instrument like MINT and low volatility hedging ETF is also down (too complicated to understand)even mortgage-REIT is crashing as well (this one,hard for me to understand why).So far only three asset class survived: SFR/MF, energy sector and NNN assets.Private markets generally take about 8-16 months to catch-up to a sustained public market correction.

Even if the numbers work out, the sustainability of those numbers after the fact is another story based on the factors I already mentioned.If it quacks like a duck...

This wouldn't always be inappropriate if they are getting a quick cash sale for a property in rough condition.If they were a little smarter and less greedy, they might find a sustainable model of what they are doing.

That said oil may stay low for a while so there may be more fallout to come, but when you consider that production costs of a large portion of the worlds oil is 2x the current price, it is pretty obvious that the low prices are not sustainable for very long.
