@Anthony Sigala that "Rule" was created for mostly Class B properties BEFORE the Great RE Crash of 2008-2010.Values after the Crash dropped so much, that it could also be used for Class A rentals.Values are now more than their pre-crash highs, so the rule now only applies to Class B & C rentals.How are you identifying Class B & C submarkets in your area, so you can properly apply the rule to the right rentals?

Some will probably do fine with it, but the number of spectacular crashes amongst this demographic will be a multiple of the norm. 

Here are a few ideas I’ve seen work:Gap Funding (Second Position): Risky—like lending your buddy cash to fix his car, hoping he doesn’t crash it.

Due to 21 and 22s boom in MTR/STRs in Eado/Third Ward, this was flashing all types of crashing signs and you dove head in first. 

I know of no RE investor that had RE before the crash that did not exit that would agree with your statement including this investor.  

When the market crashed, we went broke.

Even if buying a property Subto in GA and you live in FL, you could miss something and the whole deal does a "crash and burn".

Just adding my $0.02 here, I just tried to add a post through the app and it crashed as I hit post.

@Chris Mahoo many new investors don't take the time to properly understand RE investing.1) Many are using approaches from 2010-2018 when Class A property prices were so low from the Great RE Crash that an investor could cashflow and get pretty easy Class A tenants to manage.2) If you look at what investors were doing before 2008-2010, most were buying Class B & C rentals.To make it worth while, an investor either needs to Fix & Flip or invest & hold rentals for 10+ years.- Over a 10 year period cashflow will increase as rents increase (rents typically rise faster than property taxes, insurance, etc.)- The property should be appreciating, if purchased in a good location, increasing the owner's equity/wealth.- Rents will be paying the mortgage off, increasing the owner's equity/wealth.- If you hold a rental until death, you can pass it on with a stepped-up cost basis, limiting captial gains if then sold (limited by inheritance tax limitations).Too many newbies on this site trying to replace their day job income via "passive" real estate investing w/o digging deep enough to understand how it really works.
