@Nate WightmanI like modular for speed of schedule and being built in a controlled environment as opposed to out in the elements.

And then trying to convince the masses that there is no competition on the MLS.. for Pete's sake, that alone should make people run away yelling "scam".On the MLS, you are competing with real estate agents, that buy houses themselves on the MLS, you are competing with the traditional buyer, you are competing with other investors crazy enough to try to look for deals on the MLS (yes there are plenty), You are competing with agents that look for deals for their list of cash buyers.Every single element of this entire thing is just retarded. 

Even you calculate the depreciation expense by yourself, accountants usually calculate it by themselves to make sure that the numbers are correct as depreciation expense is one of the biggest and most important element of your tax filing for your real estate property.If you like to take a look at the actual IRS guidance, here is the link. 

What elements make income properties profitable?

The only way to handle criticism is to foresee it as an element of your success formula and push toward it.

Also, Im not a tax professional and this is not tax advice, but your CPA should be able to claim you deprecation on your investment as well, gaining you even more tax benefit.Solar panels provide cover from the elements to the shingles located below them, thus increasing shingle life.

While there are certainly many people who have done successful deals without having deep experience within specific markets, there's likely an element of luck involved.One of my work colleagues used to manage a team of commercial multi-family loan officers for a major bank, and he has another angle on what valuable experience looks like.

For me, it also depends on exposure - I would be unlikely to paint brick that has heavy exposure to the elements, i.e. is not under a deep covered overhang or was a two-story design.

However, to the untrained, it will be difficult to determine what all of those costs are, and even more difficult to apply them according to the rules set forth by the IRSPlease see the IRS guidelines of how to prepare a quality cost segregation study https://www.irs.gov/businesses/cost-segregation-audit-technique-guide-chapter-4-principal-elements-of-a-quality-cost-segregation-study-and-reportThen you'll need to ask yourself is it worth the hassle, and expense.
