Population Size - Greater than 1 million.

What is the lot size? 

I'd be networking out to wholesalers, absentee owners, and many would-be deals in order to bring anything I found to the table.

Use Private Money or Hard Money Loans to minimize what cash you have to bring to the table (if any, if you use PML). 

Not sure how many occupants, but someone told me and it was more than you'd think from the size.

If it's a straight R10 and the zoning hasn't changed then there shouldn't be a problem unless it's in some sort of a UZO or historic.It needs to be min 10k square feet lot size. 

But they are the size of 20-40 school buses stacked upright and on top of each other.

Right now, just about all I can do is analyze deals and bring them to the table.

Meaning no agreements that are not disclosed to the lender should take place all parties are required to sign Means no rent backs or cash under the table.

Buying a multiplex with reduced rents will affect new buyer's cash flow/profit and is sure to be reflected in the price the RE sells for.I gave out 6 maximum allowed rent increases this year having never given that size rent increase previously.
