It's not uncommon to bring in structural engineers when you're doing work that will impact the structural integrity of the house. 

But even the best brand that is well installed will fail if you neglect to remove build-up of environmental conditions - allow the compressor to swim in horse manure and the air-handler and duct work to be dirtier then a wood-burning chimney.Most new installations should warranty their labor for 6-12months at least, and therefore most will generally offer to perform first 1-2 PM services for free.So, assuming you don't have a lemon product - which you'll know during the first year anyway - the ongoing preventative maintenance on a good, properly installed central AC system can really be done by you, or anyone working for you:1.

Any clues on how my year end taxes (not property taxes) will be impacted by purchasing a home, and now having more income coming in.

Trying to get feel for frequency of environmental studies done on commercial properties and if phase 2 done specifically for underground storage tanks would additional study need to be done on individual structures?

We are planning to do our first deal(s) before the end of 2015.I currently have a well paying job with a reasonably high net worth and we have great credit so we expect to be able to get favorable loan terms.We are primarily looking at buy and hold single family rental properties as well as smaller multi-family/apartment opportunities (2-20 units to start).We intend to form a corporation to hold our properties and gain tax benefits.However, we are talking about doing this full time (I would quit my job at some point) and we were unsure what the impact of this decision might be on our ability to get loans.
