New here! About me, my beginning plan, and a few finance issues

[Bradley Britt]

Hey yall! My name is Cole and I'm from middle Georgia. I own two small businesses and currently 1 rental property. The rental property I have is our first home which was an FHA loan and cash flows 425 per month.

My Background: I'm 35, with a wife and 2 kids. I have a law degree (never used it technically) and am now about to take the real estate exam. I'm taking the exam so I can put my own offers in and have access to MLS. Also, I feel like it may put me in position to meet people and a good way to learn. My other two business are still my main priority as I build this on the side.

Plan:  I want to stick with buy and hold.  I want to find houses that cash flow at least 300 a month and my range is 80k - 150k.  

Issues:  Being a small business owner of businesses that have alot of expenses, it is easy for me to keep my taxable income down, and by down i mean WAY down.  My wife and I jointly are at about 30,000.00 per year.  Next year I will probably buy less equipment and try to keep it at around 50k to help with buying.   Whats our best strategy for buying houses?  Id love to buy 1 a year.  We have some money saved up and early 2021 we could put 20-35k down on our next rental.  My wifes credit is excellent and mine is good.  Our issue is with the low income.  Does anyone have ideas or suggestions?

currently our only debt is our two mortgages, 1050 and 720 (but this one is rented for cashflow of 425)
