The bank will prohibit assignments.The bank will require that you demonstrate that you, personally, have the ability to purchase before they will even look at your offer.The bank will require that the property not be re-sold for some period of time, probably at least 90 days.The bank, and I say this with all due respect, almost certainly has a better idea of the market value of the property than you do.

I am having trouble structuring the deal because the lot is zoned RLC which has a condition that states that only a law office can be built on the property. 

Roof condition & number of shingle layers.

It's a 2/1 duplex in San Jose, CA (off of 10th & Julian). 800 sq ft, older property but in good condition.

The property has been rehabbed and is in good condition.

The Lease needs to be clear in its definition of what you are trying to accomplish here which is that the Tenant pays for all of the operating and maintenance expenses of the property.In addition be sure to include an understanding of who pays for major capital replacements (not just maintenance) such as replacement of the heating and air-conditioning units, water and sewer lines, electrical mains, roofs, glass, etc.

I'm going to do as many deals as I can while the market conditions are favorable.

You could make it a condition of the sale that the home is vacant before closing on it. 

What condition is the property in?

If by chance you took pictures of your place before leaving, attach those as well to show it was in good condition.
