I am normally aligned with your thoughts but we may be misaligned on this one.Offering packages may say 5 or more years for conservative purposes but many have plans to sell or refinance (supplemental loan) after the value add to realize the sponsor compensation on the sale, eliminate/reduce the preferred return, and to maximize IRR and increase the velocity of capital. 

In sum, even if you only have enough money to do "one at a time" that does not equate to doing one per year... the velocity at which you do them increases as you become more practiced at doing it. 

buy land get it up zoned and approved for HBU and flip timber tracts that you can instantly log and resell we made millions doing this on OPM .. and it viable in the Carolinas etc.since its a full time gig you need to look at more robust ways to create income than as you already understand drip income is not going to get your were you need to be in a short amount of time.. rentals is a very LONG game. so you need to be looking at crap properties that can be turned around and resold if you can do them in 13 months you get cap gains.. and or rent them for a year or two and you can roll up for a 1031 and keep velocity going that way.. but again I would not be so keen on just giving up 300k a year  many of the landlords on this site can get to that 5 to 10k a month and that's all they need to live on.. someone used to larger income that usually wont cut it.. so scale has to be huge to replace 25k a month..

Personally I am looking into BRRRRing as much as possible increase velocity over time. 

Imagine if a person created money velocity by reinvested the tax savings each year back into their real estate business instead of cashing out ?  

Equity sitting in your properties is dead money and by leveraging those properties to access that capital to finance other income producing assets, you are increasing the velocity of your money.

This doesn't make it a bad deal, it just hurst your velocity of money as you have less funds to go to the next deal.  

(leave 34k in the deal and refinance at a later date)Just finished reading @David Greene's book, and learning about the velocity of money concept of using cash and refinancing and using for the next deal.

@Derry Johnson the BRRR method has to do with the velocity of your money, and it can be utilized anywhere.

Chantilly's market will not increase with the same velocity as properties closer to the beltway.
