. :-)Here's what I would assume based on it being an 1100 sq ft home.3bdrm, 1.5 bath.So a full gut:1) 10 windows = 5k2) Siding = 4k3) HVAC 4 to 5k (furnace and a/c)4) Electrical (rewire and new panel) = 4k5) Plumbing = 3k to 5k (assumes crawl or basement - if slab, this price is much higher) depending on if you're moving anything or not.6) Full bath with tile surround above tub (simple pattern) = 5k7) Half bath = 2,0008) Kitchen (cabinets and countertops) =6k9) Light fixtures = 1,80010) Roof = 4k to 5k11) Flooring (carpet for bedrooms and family room, tile for kitchen/dining, bathrooms and foyer and need durock under tile) = 5k12) Drywall reparis - 1k (I'm assuming you'll need some drywall work done but not necessarily have to resheet the entire house.

Then use white subway tile for the backsplash.  

That said, those who are commonly thought of as subcontractors (painters, tile-setters, etc.) and want to contract directly with those other than licensed Contractors, then they must have the MHIC Contractors license and not merely the Subcontractor one.  

The floors in each bedroom unit were 1'x1' hard tile which could be pulled and replaced individually.

In fact they are the old open brick fireplace with ceramic logs that have a live pilot.  

I don't have anything to offer with your question beyond what everyone else has said but I just want to let you know some general rules with foundations:1. crawlspace - cheapest to repair, good for plumbing because they can run underneath the house and easy to repair, bad for really cold days, pipes could freeze, some people complain about moisture in crawlspace and tile cracking but that's a long term issue and you may not have to deal with that and if you do, just lay LVP2. slab - second cheapest to repair generally, worst for plumbing because to fix, you have to often remove flooring and drill into the concrete to fix leaks and I've had a house that I played whack a mole with an active leak3. basement - most expensive to repair, okay for plumbing, but your basement could leakIMO crawlspace is the gold standard for foundation for rental investments in older properties (older than 1950s).

Manolo, you referred to mid grade finishes costing 30-40/sf less than higher grade finishes so does that mean that you have included all the fixtures i.e. tile, sinks, showers, tubs, lighting fixtures, appliances etc. in your 150-180/sf estimate?  

The only floors that come close to that are tile - with epoxy grout. 

The biggest value add were the full kitchen with taking out a wall to open it and adding a pantry, Tearing up the old tile and vinyl and laying new luxury vinyl water proof floors with beautiful tile in the laundry and bathroom, and also the full primary bath remodel with adding a standing shower, and the new exterior paint and landscaping.

New paint, new tile work, new cabinets and countertops, all made this house shine.
