I see pros and cons of both.Doing it myselfPros - Save labor cost, Develop standards for future repairs, Use saved repair costs for next investment?

Pretty much standard verification on the property the ownership, when I closed, what I paid, improvements to the land etc.

That is very important to know you can not use standard financing through homepath, must be an approved lender.

Take it as a 'standard' in your Life that, for you;  there is no such thing as giving up.    

Also, assume all of your standard costs associated with buying, rehabbing and selling a property.  

I don't quite see an owner being OK with someone purchasing their house via owner financing or Sub 2 and then immediately moving in standard tenants while charging them rent, though.

I normally put a sign in the yard as soon as I close on the house, but I don't normally have a rehab take longer than 30, at most 45 days.It's never caused a problem, but I don't let them pick the colors, etc,,I tell them it will be our standard colors/finishes, and show them pictures of previous houses.I prefer not to sign a contract until I am far enough along with the rehab that I know it will be ready when the move in date comes,,,I have literally finished the rehab in the morning and have someone move in that afternoonandy

Standard conventional with 25% down.  

Use a standard form, if that makes you and the seller more comfortable.

The standard wait time with Fannie Mae is 6-months for cash out, so look for a lender who offers delayed financing if you're going to complete your rehab in under 6 months.Best of luck!
