When I see "boiler" I read that as radiant heat, whether that be hot water or steam.

-A & B Class Tenants tend to prefer gas for cooking and heating (although SoCal has very mild winters).

I know a flipper who told me about installing an electric baseboard heater in the house during escrow so the house would have a heat source and qualify for a loan.

Do you pay heat or do they?  

This will give you an advantage when negotiating and also will open more doors for you in terms of property condition if you are looking for a house with a value add element. 

This has proven to be very durable in my rentals and is heat resistant.

Complete the renovation and then find a one-year renter at a time when the market is heating up.

In other words, in this over-heated “sellers’ market,” sellers are selling their homes for the listing price or greater.

Does the lease say no heat until 10/31?
