I had a super old, cast iron boiler in one of my properties that had to be replaced. 

Silver Spring was one of the final cities Amazon was looking at for HQ2, ironically it is not too far from Alexandria.

I have too many irons in the fire at the moment.

A CPA is 100% the person to give you a specific answer on that and iron out the best way to strategically execute. 

Due to the restriction in air flow it would create we did not reinstall it but left the furnace without a filter to prevent damage to the furnace.PLUMBINGThere is a cast iron sewer or drain pipe on the floor of the South side of the basement, there is an open clean out missing a cap or covering on this pipe.The drain below the bath tub was leaking/dripping during today's inspection.The service wire to the water heater is not enclosed in conduit or a protective covering to guard against accidental damage to the wiring or its sheathing.The water heater TPR valve is missing the extension pipe to the floor for safety.ELECTRICALThe house has some of the old knob and tube style wiring.

Ironic thing is that all the regulations actually have the opposite of the desired effect -- they just serve to increase prices even more by restricting market mechanisms..Originally posted by @Amit M.

Having an iron lease is our first priority.

Yes, whole Seattle area is tenant friendly but, I thoroughly screen my tenants, set expectations up front and have an iron clad lease, so I haven't personally had any issues with the renters here.

:Thanks - I'm now starting to think it's cast iron...same concept?

When we have too many irons in the fire, we usually get burned.Good luck
