I would not engage a realtor. They will rightfully want around 3%. If you don't have a way to get property profile, don't worry. Just write up the offer based on what the seller tells you (and verify with mortgage statements). Your purch agreement can have a clause about price based on what you expect and will be adjusted should any surprises come up that the seller "wasn't aware of".
Unless you have construction and/or flip experience I wouldn't flip this as your first. I would either Jv w an experience flipper or wholesale it.
There a lot of ways to monetize a good deal. From my perspective, for a first deal I would tie it up and wholesale it to a cash buyer. By his will hopefully begin to build your war chest so that after a couple of wholesale deals or JVs, you can take one to completion on your own. This will accomplish a couple of things. 1 you will get experience negotiating with sellers and tying up deals. 2. You will beginto build your cash buyers list which can be valuable. I found it much easier to find true cash buyers once I had a real deal to present to them.
Keep listening to the BP podcasts as well as Michael Quarles podcast and Sean Terry's podcasts. Between these three and the BP forum you will gain the knowledge you need to be off to a great start.
And nothing beats taking action like you are and learning in the real world. I commend you for doing it!
Good luck.
