Newbie Investor - Investment Plan - Please Help - SOS

[Lamart Gomillion]

Hello All,
I am new to the RE world, but have been tracking Biggerpockets forums for some time now. I am here to draw out a plan, and would like you know what you Ladies & gentlemen think. My plan is only for Mult-family units at the moment, and I currently live in Georgia. The plan is as follows, I will purchase 4 Multi-family quadplexes this year, at an average total price of 120,000. Each Multi-family property goes for 525 totaling out at 2,100 per month. With 4 buildings this goes for 8,400 per month, totals out at 100,800 per year gross. Now for the expenses, all 4 properties will require loans, since I am putting 20 percent down, I estimate the mortgage payments will reach around 650 per month for each building totaling out at, 31,200 yearly. Maintenance I expect may be around 5000 per year for each building which adds up to 20,000 per year. Property taxes should be around 1,600 per year total. Property Management is estimated at 10 percent 10,080 yearly. Net profit is only at 37,920. After the 4 buildings have been purchase my plan is to leverage all 4 with equity only by half, and pay cash for the other half to finance 4 more properties so I could have 8 total. That is the total master plan, please let me know if this sounds feasible, I am currently 31, credit score is around 720, and yearly income is around 140k from my Job as a contractor overseas where I have been employed for 7 years. When I get all of these loans, I plan to leverage a little bit by paying them all up 2 years ahead of schedule. Please let me know how this sounds for a newbie, have been studying this stuff for some years now, and am ready to pulll the trigger. I do realize I may need to mix some flipping in with this plan to pay off these loans quicker, but my main objective is to phase out the need for a job, and I will add in flipping at a later time, plus I have not done as much as research on flipping as I have with buy and hold, flipping seems like a waiting game, but profitable. Forgot to mention that I do have 1 property that is being built in Thailand that I do plan to resale. Another question is tax benefits, how much of this can I write off? Please please let me know what you guys think, your help would be greatly appreciated.
