So my question is there a way to move the mortgage on me without paying any additional cost like closing cost and gross receipt which usually paid by sellers?

Plus, during the restoration/renovation process, if unforeseen things are discovered, they'll submit a supplemental claim to account for any additional cost.

I just wanted to make sure there wasn't an additional document/steps that i needed him to sign/do before i went to the title company.

If for some reason the Seller gets me to agree to modify it to say “Up until 12:30 AM on XYZ date...” then I better be prepared to lose my EMD at 12:31 AM if I don’t exercise my weasel clause by 12:30 on that day and somethings goes wrong later.  

You can also try to negotiate one or two extension options in the loan (you will typcially have to pay an extension fee and meet certain requirements to be able to exercise the option)

This additionally applies to your Vacancy and Repairs reserves. 

First, are there any additional steps that I missed?  

However, if they wanted to justify it, I'm sure the justification is that renters cause more problems than owners; renters tend to live then shorter periods of time and there are expenses when someone moves in/out such as extra trash pick-ups, programming them into an entry system, cleaning costs as the move in/out can be messy around the building, light damage to the building, scheduling of the freight elevator, cost of providing additional notices as now the tenant and owner need to receive copies, etc.

Here are some tips that I sometimes put my offers on if I were representing my buyer(s) especially on a hot market like it is down here in South, FL.Deposit = $5% of purchase price Additional deposit = $5k-10k upon offer acceptance.

This adds an additional layer of risk and you really have to be careful here.
