Quote from @Jamie Hora: The question you pose in the title, "Is a rezone required if availability study can support more density". 

Please study engineering and you’ll have more of a grasp of why measuring amperes (electricity) or volume (water or natural gas) lends itself to reasonable precision.  

Due Diligence and Feasibility Studies - What studies or tests are essential before purchasing raw land?

Studying for and receiving the CCIM designation will be a solid plus.  

Quote from @Melanie Baldridge: A question that we get:"Does the IRS require site visits for cost segregation studies?"

Financing is definitely an area that I will need more study.

We have seen properties for as low as $100k benefit from engineered cost segregation studies. 

What you can do to offset this profit is to invest in syndications that do cost segregation studies (which will lower your tax you pay).

We purchased a property in early October and are placing it in service this week (mid November).We had intended to run a cost segregation study and try to accelerate depreciation which we can deduct against our W2 (assuming material participation).However, we have been reading through the IRS guidelines (eg publication 946 on Property Depreciation) and there seems to be the concept of "short year" which would mean that we can only deduct ~1.5/12 of a year's worth of depreciation in 2024.Is this correct or are there any different rules for STRs specifically?

Study up on warrantable vs non-warrantable condos.One idea I think for a fresh grad, is to find a great RV park operator.
