yes, I pretty consistently offer an add on day at a fairly steep discount.

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

I would have the draftsman draw up as much as they can for the plan and THEN get the structural engineer to add on and sign and seal.

It seems each year a landlord needs to add on to the list.

It looks like an add on.

Depending on your location, you would probably be looking at the following for 10,000sf and 13 units:- Sheetrock, Tape, Mud: $25K- Paint on Fresh Sheetrock: $25K- Cabinets/Countertops: $25K- New Plumbing: $25K- New HVAC: $25K- Appliances: $25K- Bathroom Tubs/Vanities/Mirrors/Toilets: $25K- New Electrical: $20K- Cheap Flooring (Carpet + Vinyl): $15K- Exterior/Interior Doors: $5K- Windows: $5K- Electrical Fixtures: $5K- Plumbing Fixtures: $5K- Water Heating: $5K- Trim: Door Knobs, Outlets, Switches, etc: $5K- Permits, Dumpsters: $5KThen, add on the 10-20% overhead of having a GC manage it all, and you can see that it's easily on the order of $275K, or about $27/sf.This is for low-end interior gut rehab, and doesn't include exterior rehab, and doesn't include any of the higher- level of finishings you would want to use in a house that you would be retailing.Add those things in, and it's easily $30-40/sf, which is the number that I generally use in my area.

Does that just add on when the renter's credit card is charged?  

We say we want to add on to one of the houses to get more space.He says “It’s not gonna happen.

As an add on, I suggest thinking a bit on some other thoughts such as @Corby Goade added here.
