If you're living under a bridge, moving into a house or apartment will dramatically improve your life. 

@Yonah Weiss I asked a CPA about bonus depreciation and this is what he said:"The new tax law changes bonus depreciations for qualified improvement property paid for starting 9/28/2017 and on, however rental real estate is not “improvement property”.

I am going to practice everything and stay in contact with many of people interested in RE as I can.

The 2017 Florida StatutesTitle VICIVIL PRACTICE AND PROCEDUREChapter 83 LANDLORD AND TENANTView Entire Chapter83.51 Landlord’s obligation to maintain premises.—(1) The landlord at all times during the tenancy shall:(a) Comply with the requirements of applicable building, housing, and health codes; or(b) Where there are no applicable building, housing, or health codes, maintain the roofs, windows, doors, floors, steps, porches, exterior walls, foundations, and all other structural components in good repair and capable of resisting normal forces and loads and the plumbing in reasonable working condition.

Certainly with an older building that has been mom and pop managed for 30 years, there are plenty of opportunities for improvements that don't necessarily equate to added value (hot water heaters, French drains, new electrical service, etc). 

Basically, no matter what software or tools you use to analyze rentals, you want to practice with them until you feel very comfortable on how the process works.Another note, is that what I often see is not so much as mistakes in the calculations (if you use a tool/spreadsheet, the likelihood of this is small), but incorrect "inputs" into the calculators.

Instead, practice getting better on the one you have now.

I'll be "house-hacking" the property and making various improvements to the unit I'll be occupying as well as the building facades, and backyard.

I'm sure that with some training and practice you could master all of the below:marketingrehabbingsellingmanagingevictionsdrawing contractskeeping booksetc.Yet you do not (I hope) do all of it yourself.

Kyle, it's not a rocket science, just common sense accounting practices.
