The condensing unit or heat pump,will need a dedicated 220-240v service.

Exterior work includes windows, siding, A/C condensers.

bring gifts as he figured out what would work for each  ( nothing extravagant)  make sure they had his number and call if anything looked weird so these folks got invested in the project..  35 new builds 7 years later I can tell you we have never had a break in or theft KNOCK on wood cant say that about our rentals though i have had more condenser units stolen than i have digits. 

I also would like to have the tenants responsible for all utilities, so I would need to install two seperate HVAC units (2 furnaces, condensers for AC etc.)

Furthermore, there was no A/C although a condenser was sitting outside, there were two furnaces, neither one of which worked, and a mess of DIY electrical and structural projects throughout the property. 

I also think part of the inventory dropping is because the market is condensed this year.

I talked with him and he said this info is out there, but he condenses it and makes it digestible in a short period of time, which was sort of my take on it.

You may be able to condense it a bit but it gets the message across.

That said, the big issue you'll run into with conventional loans on an investment property is that the lender will require an inspection, and if the property isn't move-in-ready, your loan will likely be denied.Even minor issues like a non-working water heater or a missing AC condenser can mean the deal won't get funded.

What we saw stopped us in our tracks: the AC condenser was missing!
