I have excellent local contractors to do the work as well, and estimated repairs are around 15-20k keeping it on the lower to medium end.

Do I have to prepare extra money in my self directed Roth IRA for maintenance/repair/tax/insurance if I invest SDIRA into  LLC ?

Well, buyers sometimes want wacky repairs based on their inspection; if appraisal comes in a good bit above contract, I might be more willing to avoid agreeing to repair everything - especially if I had to give a seller assist.And if I have another nearby property to be sold soon that is similar, I can use that appraisal to help come up with a better asking price for that other property.

I wound up delivering our 2nd son on the side of the road while on the phone with the paramedics.  

Doesn't look like it needs any repairs.

I was planning on using the BRRRR strategy for my first 5-10 rentals and I want to keep this property as it will have a ROI of 15%+ after the first year, as well as a ARV of $110,000+ (low side) after putting in $30k in repairs ($5k buffer) and I paid $0 for the property.

If you are tight on cash flow, it is recommended not using reserve, but these days we have credit card that can cover the unexpected repairs, so not using your reserve for other deals might be bad financial decisions. 

You could pay them a little extra to restock supplies and let you know about any repairs that are needed.
