So someone who is looking purely to maximize potential return (and has unlimited time) is unlikely to find this a good fit.Here are some good websites for seeing the variety of deals that are available for hands-off investing/passive.1) CrowdStreet.com2) 1031Crowdfunding.com3) Ark7.com4) Finresi.comGood luck!

Even one vacancy or non-paying tenant could potentially be a major problem.And yes, there were vacancies, and non-paying tenants, and major problems.

If your giving away 30% of Gross, that severely eats into your potential profits. 

.- Many of these HCOL areas also have strict limitations on AirBnB or short-term rentals... that do not apply to owner-occupants - thus allowing for extreme cashflow potential for house-hackers.

The potential problems mentioned by the responding posters in this thread are real and well thought out.  

. -- and they find deals that could be good for all of them - and everyone is helping each otherI think BiggerPockets will be a potentially pretty reliable place - I know that there's different roles, "finders", "buyers", "sellers".... maybe I can just find deals, and connect people together, and get some kind of small finder's fee for it, or something.... ok so that first 10-20k is important to just be able to provide - when getting into this....

Quote from @Christian Styles: Potentially able to help you find someone but I would need to know specifically where the property is in order to know who to recommend.  

He believes that area where he will be buying the new homes is going to appreciate and attract more MTRenters, but now, the big difference is that he would now have 3 properties that can go up (or potentially down) in value, go up (or down) in rent, and three times as many vacancies to fill.My back of the napkin assessment is that for only a drop in $200 a month in cash flow, he would control a lot more assets with growth potential and as rents rise over the coming years, the combined rents will increase to a total more than the single rent.HOWEVER.

@Isua Mbang I haven't used this product but it comes and goes under different monikers, velocity banking/all in one loan/accelerated primary residence payoff etc It could potentially work but keep in mind that most people don't have stable enough finances to make this work.

., giving you market guidance, open houses, vetting potential buyers who don't have and don't want representation, contract negotiation, managing/scheduling/attending inspections and surveys, fielding bank requests for information, making sure government paperwork is done, you imagine and write it down and you'll still miss some stuff, but that's okay.
