What i did not have to do while owning them though was roof plumbing elec appliances stuff like that.. those lasted a good long while..

wow never seen flat roof designs in that part of the country. 

There SOW would usually be - 'I want a remodel done on the kitchen and bath, and add a new bedroom on the left side of the house'...Then I would add items that only a GC would know about or notice, like needing new headers for the openings they want, the elec panel being undersized, or the roof being suspect, etc...Together we would then arrive at a comprehensive SOW.Yes, that is much better scenario.

A buddy of mine, who’s been an agent in the Phoenix market for nearly as long as I have, once had a client who stumbled into a 1031 that shot their returns through the roof because they snagged a property near one of those new tech corridors sprouting up.. from what I’ve heard, that corridor’s been buzzing with interest lately.What’s exciting right now is seeing how investors are leveraging 1031 exchanges to pivot into markets that are on fire.

While this works, it’s not always a true “turnkey” setup.In other cases, the entire process—acquisition, renovation, and management—is handled under one roof.

HVAC is assumed, as is roof, so that doesn't push up your value much.

Metal trusses and roof.  

Took soffits down (whoever invented soffits should be shot if not dead), new flooring, new paint, new roof (thanks hailstorm), refinished the deck.

If you are doing multiple renters to one shared roof, then do yourself, your investing dreams, and your renters a MASSIVE FAVOR by learning & implementing coliving property management. 

For older properties, expect a higher CapEx due to potential issues with major systems like roofing or plumbing.
