EXACTLY!!!!!
Let me follow this up with another example based on one of my rentals in Los Angeles. I have a 4/2 SFR in Eagle Rock, Los Angeles that I purchased in 2013. It was distressed so I got a good deal. I rehabbed it after purchase with quality finishings and material as if it were a flip so I can rent at top market rate... and get good quality A/B tenants. It might have been slightly negative the first year or two... but that was ok since my equity was there. 3yrs ago it rented for $2,900/mo... then raised it 4% to $3016/mo the following year...Last year it was $3136/mo. Went vacant during early summer this year. In most markets, this is when landlords freak out... For my wife and I, we were jumping for joy. Reason is... market rent in this area is now at $4k+/mo for this neighborhood. Supply and demand is real!! We put it back up on the rental market after just some deep cleaning, paint refresh... and listed it back up at $4100/mo just to see what happens. We received more than 10 calls the first day... and got 4 solid applications within 3days (mind you, these are A/B applicants who were voluntarily providing bank statements to show proof of funds). In hindsight, I think I should have listed it higher. LOL!! At any case... That's almost a $1000K/mo rent increase in a year!!! All the while, my property value jumped up due to appreciation! By the way because of appreciation, I decided to get a refi because my LTV went down less than 30%. My Rate and Term Refi for low LTV on "non-owner occupied" was 3.75% at par rate. Its a no brainer move. This has additionally increased my cashflow even more... plus now I am available to tap on built-up equity (HELOC) to do some serious damage and play with the big boys.
By the way, for those of you that worry about property management... if you have the right strategies in place and buy at the right areas, it's not that difficult. I get minimal calls from my SFR tenants... maybe 1 or 2 minor calls a year. My rent collection is managed with Cozy. I have on lease contract agreement that they "must" have it set up as autopay through cozy and I do not accept partial payments, $50 late charge, other various stipulations to make my life easier.
Now, tell me... Can you get this kind of ROI in only 6yrs in these so called "cash-flowing" markets OOS with 1 unit?? I only have 5 rental units right now... and Im practically able to retire now very comfortably if I chose to.
My point is... Learn your market! Figure out what works. Figure out what kind of investor you are... and which property type works best that matches your investment style. There's always a way!!! Bigger Pockets is an awesome resource for knowledge... but as @Will Barnard mentioned earlier, know your source of information and make sure you are getting sound advise.
