I haven't had time to fully analyze this property, but I saw the comps and I thought this might work :(. 

Assuming thsi is a dedent decent market and the house is priced right, you’ll pass on this deal and next week it will be under contract with someone else since you obviously thought it was the best deal at the time.

I thought it should be easy, he owes me rent., I evicted him. 

If my tax preparer says I need something from all the platforms then I’ll worry about it but until then I’ll just go on about my business and report my rent to the IRS based on how much I know I receive from each tenant each month.

Now that I have an LLC that I will be purchasing the property in, what kind of stuff should I be doing to prepare for taxes etc.  

I know they used to have free tax preparation where I was stationed.

We had thought about that, but we weren’t sure if location would work.

great thought put into this.

I currently own a SFH (2 bed/2bath) that I bought before considering this strategy and any thought about renting it out.

Considering FHA 203k for your BRRR adventure is a solid option, but here's the lowdown: prepare a minimum 3.5% down plus renovation funds, stay within FHA loan limits, and understand the refinancing process after a 12-month seasoning period.
