I know people talk about different markets outside of Oakland quite a bit on BP, but depending on where you work, you need to be Bartable and even then you don't want to be Barting an extra hour each day to save $10K spread across 30 years (just my 2 cents).On a 3-4 unit, you will likely run into self-sufficiency issues if you go FHA (most don't cover here).

The lender "pads" the escrow account at the outset so there are sufficient funds in there when taxes and insurance increase.

In addition his Rental Track record (2+Years) most likely will be sufficient for most lenders to count his Investment Cash Flow as Income. 

Most of the ozone generators available for less than 300 bucks do not put out sufficient ozone to "Shock treat" a room.

If I use 65%: $1260*0.35-$340=$101The difference in the cash flow projection is likely in maintenance/cap ex but if you did not include vacancy and PM that could also explain the cash flow projection difference.BTW neither of those are sufficient cash flow in my opinion for owning 3 units but at least they both reflect positive cash flow (positive).I hope that I am incorrect and to be honest I do not have experience at that low of a rent market (I have OOS experience but not at that rent point).Good luck

That would have been sufficient documentation for a judge IMO.

Specifically those who are cash buyers, those with access to hard money or who have a sufficient line of credit.  

(sweat/elbow grease equity) with you being home with the little ones you would be right there capable of handing concerns / repairs or calling contractors for the repairs in a timely manor, also doing / overseeing work / rehab on the units, so you could use being home full time to your advantage, and with school you will have that open block of time. i also understand that money is tight, it takes 2 in most cases to make ends meet these days but you guys sound like you have your head on strait an moving in the right direction to get out of debt and into a better standing point in your new location. but YES the idea of house hacking is to have the cash-flow pay your mortgage and if you have the numbers right, have the possibility to put a dollar or so in your pocket above expenses but do not expect allot above the payment for your first investment. but one thing to ask yourself is *what can i handle*  can you handle dealing with repairs or rehab or if not can you set up contractors to take care of your interests since i assume your partner is or will be still working. a duplex would be sufficient to start with to pay your mortgage if the rent comps/market allow it to match your expenses, but myself. if i was to house hack it would be a tri-plex or bigger,  yes it would be a challenge but if a duplex pays the mortgage think about the income from a tri-plex .  

By the same token, don't get caught up in analysis paralysis either. 

I really proved to myself how much I am capable of, when sufficiently motivated.
