not true. we build a stacked triplex. 50k land, 300k hard cost, 10k soft cost, appraises 500k, rents for 5k a month. total return of capital within 12 months. we build at 20-25% equity because it's direct to developer and general contractor. we are vertically integrated.

I believe that is a reasonable requirement.

I have to be present all the time to make sure they are doing the job, and it's hard to keep a handyman because of this reason.

At the end of the day it's a straight math calculation, and making an informed bet, but there are also a TON of nuanced reasons that finding a deal is difficult. 

so most people will have to be as leveraged as possible to scale (at the beginning). as in, keep your LTV high and focus on buying 'as much' ($$) RE as possible. this is if you're doing a pretty run of the mill REI strategy like buy and hold. i came across an interesting guideline once: if you could sell today and net 7x+ your annual true net cashflow, you should cash-out/refi, or sell/1031. think of it this way: if your portfolio in a year is worth 1m market value, and you owe 600k, and have a lender that will do a portfolio loan at 80% ltv, you could cashout refi and get 200k to play with (minus closing costs). when you compare the now-lower cashflow from the existing portfolio (higher LTV & maybe different rate), to what you can do with 200k cash, THAT'S where it gets fun. maybe you lose 1k/mo in cashflow on the original portfolio (literally just made up a number, idk), but you can gain 2500/mo in cashflow with that 200k.. then doing the cashout/refi earned you a net increase in your monthly profit of 1500/mo, plus you're getting debt paydown and appreciation on "more" real estate, probably getting bigger tax benefits, etc.
