Rehab money is not fixed e.g. it could range from 100K to 120KWe have base price of property and then profit would be split 50 % to owner and 50% to us after taking out all expenses.Do I need o hire attorney to draft these documents ?

@Josh TurnerI am a licensed roofer and love doing roofovers... big money saver and works fine...people discourage it because it is less profitable...there is no evidence or facts that it harms anything.

You generally always want the seller out at closing, but they may need the money from the sale to move, so delaying the closing may not help.Yes, you need to set up an agreement/lease but have a much larger hold back from escrow, say an extra $10k or so, above the one month rental.

Why make it harder on yourself to be profitable.  

I need some of your inputs to determine which offer below would give me more profit or benefits from tax perspective. 1) First offer: $400K, which was what the listing price is for my property, with no closing help.2) Second offer: $412K but with $12K seller credit for closing help.

I was going to flip this investment property and take the profit and finish my mobile home and buy a second mobile home and rent out the first one. finish the second one and rent it out. eventually using the same process moving into a house let the rental income pay my mortgage and  flip houses. 

If it's a larger organization, feel free to inquire about their different staff qualifications.2.

I'm looking at a house that is considerably larger than most of the other houses in the neighborhood. 

Like to buy somewhat fixer uppers love in them for 2 or more years then sell them for a profit.

I do understand that PM's need to make a profit for the valuable service they perform.
