Thank you for taking the time to make these suggestions! 

You can read a book and multiple books, but unless you are out there doing it (I.e. getting bids and getting contractors to truly get you an exact estimate) you will be far off from the numbers you want and may even lose money on the flip/rehab.The best advice I would suggest in my experience is that you should get into the line of work by either partnering with someone or working with someone on some projects prior to going into a flip on your own.

I suggest using a service like Mayistay.

Do you suggest adding a package to my digital guidebook or offering it differently?

I'd suggest making sure to get a good GC/construction company for repairs.

Could you kindly suggest the best resources or methods to identify comparable properties in the area?

I suggest pegging a date, somewhere in Feb..

I'd also suggest considering a partnership if you feel comfortable with that in order to reduce the risk completely on you. 

Part of my issue was not having a reasonably priced handyman ahead of time and eventually overpaying to just get it done and also inexperience as a manager.With that said, you essentially have two options: very cheap properties in less good areas (you're looking at 100k or less--which you might have trouble getting a good lender for)  or trying to do some sort of house hack (e.g. live in flip, live in rent by the room, multifamily) where you budget will be closer to 200k-300k.Personally, I would not look at real estate until you are maxing out your 401k and IRA, but lots of folks have done significantly better with real estate than stocks and would think I'm crazy for suggesting this.

Even if you already found a PM, happy to aid to your transition with any suggestions or advice.Here for when you need me!
