Do I have to meet the realtor there or will they give me the lockbox code?

Something to look into with a properly licensed contractor capable of the work and familiar with your building codes.  

When the financing fell through and Trump filed BK for the umpteenth time, the contractor changed all the codes so no one could use the elevators to finish the construction.  

By far the most common question is "What zip code should I invest in?"

I understand the second part, just not the reason why it is advisable to take the depreciation in that case.Because the way the IRS code is worded it's required and you're taxed on the amount that SHOULD have been taken whether you take it or not. 

 - If you live someplace with stringent energy codes, consider insulation costs when framing (i.e., don't use 2x4 framing in places where you need R-20 insulation) -- this reduces your need for expensive insulation solutions.Also as Karen and others have said, buy materials that are decent but can be had inexpensively -- ceramic tile, carpet, less desirable granite slabs, etc.

-building codes everywhere are becoming more and more stringent in regards to energy use.  

If you're legally allowed to own the property I imagine you're allowed to do anything you want with it so long as it conforms to local laws and code. 

Another perk, is you can get codes to go look at properties whenever you want.

Both properties happen to vacant lots that used to have single family homes on them and have since been demolished (one for being burnt down and the other for code violations).The thing is, I'm not really sure what to do with the lots.
