I guess mainly the refinance part.

Thank you, but I'm looking for an abatement contractor to do the work mainly, and opinions/experience on doing the work. 

Note I'm not contemplating repairs / maintenance type stuff, such as sewer mains or 1) Moving a home to a new location (as in so expensive you're nuts to contemplate it)2) Replacing / significantly changing external look / structural elements / adding a story3) Replacing vinyl siding with full brick or stone all the way around4) Replacing old heating (baseboard radiant) with new, such as a heat pump and forced air5) Updating Kitchens6) Updating bathrooms7) Replacing floors (like carpet to hardwood or stone)8) Updating fixtures9) Painting

I'm a real estate agent in Naperville, and service mainly the western suburbs.

Many people even pay themselves rent and apply it to principal reduction or savings.The main advantage of owner occupancy is much more favorable loan terms as Logan A. pointed out.

Obviously, it takes more money and time since purchasing to sale, but i guess it may be more profitable.My question is:I read the main rule on rehab market is 70% rule, but i assume on improvement and re-building segment there are another rules, because we can get price above average market price.

One of the main things is underestimating the time the deal will take and deals that take over 6 months can cost more points as well as more interest.  

Standard depreciation is where you depreciate the value of the house (minus an estimated value of the land) over 27.5 years.Accelerated depreciation is where you break up the key components of the house (i.e. roof, floors, windows, hvac, etc) and depreciate them over the IRS' acceptable lifespans of each one.  

A simple scenario ex is:  Subject Property = 123 Main St.

Where in the house is the main shutoff access?
