Sell the primary and pay off some or all of the rentals. 

Because, as you might imagine, a tenant turnover will cost considerably more than $225, but as @Thomas S. mentioned, the actual insulation bill for an attic will be considerably more than $225.Go to www.homewyse.com (I love this website by the way), select "Installation", then, "insulate attic" and see that their rough estimate range is from $1.59 to $3.08 psf (labor and materials), but then it depends on whether they are insulation batts, or blown in type insulation.In any case, if the existing attic insulation is inadequate, then maybe this "upgrade" might be warranted, regardless of how long the tenant has been there. 

However, if you are invested in debt in the same deal (especially conservatively underwritten debt) then you can foreclose on the property, and then resell it to recoup your losses… and often get back some or all of your principal.And all equity investments are not the same.

You can terminate the oral agreement any time you want.

Acceptance of rent constitutes a legally binding ORAL lease agreement.

Are you looking for anything in particular or all of it?

Some hard money lenders are also able to do a refi out of a flip loan or all cash purchase without the seasoning of the traditional mortgages, rental income history, or W2 income qualifications.You can also ask what problems and risk you are willing to take.

Term: 10 years, no balloon.Specifically, how would the taxes be applied and would only a portion or all of the acquisition and rehab expenses be able to be deducted?

I think all this would depend on how active or passive you want to be in doing all this.Here are three suggestions:1)You can look for a property manager/active real estate who can help with some or all of these.2) Join a meetup group in your area, It helped me greatly in the beginning as it gave access to lots of people who have been doing this for long.

Either you are all in or all out.
