Does anyone know how much (roughly) it is to convert oil to gas heat on. 2,500 sq. ft. duplex?

Pretty similar to all properties you need to have reserves to fix things even if it's new construction you'll eventually have to replace roof, heating, etc. if you hold the property for long enough

Previously only had a ground floor furnace for heating and one window A/C unit for cooling.

The city told you that you don't need permits and it is repair, so what the public adjuster said doesn't make sense (and neither the city official or the insurance company mentioned it).With a fire, they may need to replace more than one cracked tile as the heat from the fire and water may have caused the tiles to loosen from the subfloor and there might be damage you can't see.

@Marc Possoff a few City Council members caught some heat for doing backdoor deals on the RDA lots for far below market value.

I’m currently working in Auburn AL, my house in Miami is rented out and is going to give me $500 in cash flow after refinancing.

@Aegis Fang Aegis, I use either $500 or $750 per year per door for maintenance budget.If the property has a roof, heating source, and hot water heaters under 5 years old you can also reel in the caped.  

Best places to spend your budget IMO, though, to get that good tenant that will stay a few years - bite the bullet and upgrade from oil or electric heat to gas heat if your HVAC already needs replacing.  

Currently, I have 2, 22-year-old high-efficiency furnaces that are controlled by 1 thermostat (I pay for the heat) and window units for AC which the tenants pay.
