Yes you can use zillow/apartments.com/Craiglist, but the most success i have personally would be FB Market place.

These are very personal decisions.I can't tell you how many times I had a seller pay me to go in and redo kitchens and baths, and then get called back by the new buyer to redo the brand new custom work....just because of color.I would just put the house on the market and price it a little high, maybe $20k...?

If you can go to some in person, all the better, but even just looking up FB groups for investors in that area or even "real estate" in that area. 

Another thing to consider is that if it was your personal residence, you may be able to exclude some capital gain income if you sell it within a certain amount of time.Best of luck.

I appreciate any insights or personal experiences you can share.

Without an agreement: the Buyer is your customer and the seller becomes your client because they are the one paying the commission. 

I guess the proxy might be what the person is paying now provided this isn't their first. 

Even under this scenario, with a 50/50 split, you will not be getting paid for doing all the work.Another option would be for you to put in 50% of the purchase price using an LLC that you own 100%, borrow the remaining 50% from your investor as a 2nd position loan at a fair interest rate with points, and borrow the rehab under your personal guarantee.Better, if you can find a lender who will lend to a newbie, and they are out there, you could borrow the purchase money using some of your cash as a down payment, as well as all the rehab funds using a construction loan.

In my case, I will be making a personal offer from myself, but the financing will come from my LLC.
