Required documentation is dependent upon the length of time the borrower has owned the property.Rental Income – Subject Property For FHA MortgageLimited or No History of Rental Income Defined as when the borrower is purchasing or does not have a history of rental income from the subject property since the previous tax year.

I am working on a Subject-to deal and wanted to know how much transfer tax I'd pay on the deal.

@Juan Ayala  I have a couple attorneys I have worked with for owner-financed and subject-to proeprties.  

Small town guy from/in Texas, looking seriously into getting into the "subject to" side of the real estate market.

Such deeds can still be subject to buyer's equity/foreclosure laws. 

Try to use a combination of  a subject two lease and and equity buy in.

Luck is discounted because of the belief it is not subject to our control.  

Finally, are there any good books on the subject ?

If you find out they do, please let me know so I'll  be better informed on that subject.

A better option might just be to do a subject to deal or seller financed deal but if they are unwilling to give up the title and deed then go with what you're doing.
