The panel should run you about $800 installed.

A new gas furnace will be installed in the attic for the 2nd floor and includes all new supply and return duct work.

But for that price, I would be doing all the demo first and have the tub on site when the plumber shows up.Does this guy simply not want to do that job and so is pricing himself out of the work, or is that really what I need to budget for a simple tub install???

Several reasons to rent to own prior to financing:  1 tax code, you can only take installment sale tax treatment of seller financed sale if the property was an investment (rental), 2nd is long term cap gains, 3rd is check out the tenant for reliable payer...  

Contract for deed / land contract / installment sales - any of those actually creates an "owner" as well as occupant; used to be that one of those arrangements would be used and structured so that the occupant never completely fulfills, so in the end the deed stays with the grantor / previous owner.

The penalty is really designed for big businesses like Home Depot who have thousands of independent carpet installers, ect.

I hear this can cause legal complications for the landlord if he installs them.

(including pro installation).  

Instead of going the multi-unit route, I got into financing through lease options and instalment sales.

Tenants might install water beds, etc.Ask what kinds of rents policies you should require of your renters.
