After wholesalers determine it's a good deal then they double close on the property.

It is impractical to change the engineer at this point.I think this is a pretty common problem, very much like being presented a change order (on a time and material basis) by a General Contractor, except it is much hard to determine the time needed for an engineer to finish his job.How do you deal with such a situation?

Trying to research as much as i can before bidding on a property.I have access to public recorded documents, such as mortgages on properties, however on properties that have multiple mortgages to the same person on the same house through the same lender, i cant seem to determine which lien holder position is foreclosing (1st mortgage or 2nd mortgage). 

How do you determine what to offer on a house?
