Do not buy into any packages these so-called "experts" are selling.

The problem is that it looks like my dad's company uses a relocation package with chose real estate agents to use.

I would present a little package to a few of them and see who bites, assuming your finances are in order I think you will get some interest.

Is it better to sell separately or as a packaged deal?

Some lenders will finance these and some will not.You will need at the very least what's called a lender package from the architect.

Existing company does not do small property packages any longer and will not write a new policy.

Whatever you do, make sure you run a full screening package (credit, criminal, and eviction) on all applicants as well as an address history report to check their past landlord references.

The weird thing is that while you will not likely to get a discount on any property because a property has an old HVAC unit, a new(er) packaged HVAC this is of significant value.

I bought their package via Groupon for under $200.  

So I met a wholesaler who purchases packages of houses from banks (obviously wasn't wiling to give me any other information than that as the DFW market prices are getting higher by the minute) and I began to wonder how this process works.
