I doubt Community College will teach you anything you will ever use to make money in this business.If it did, the teachers would all be driving Rolls Royce's and living in multi-million dollar mansions--they are not.If you want to learn about SFH's (the bones and the guts of them) vs being a hammer swinger putting up framing (which you don't need to go to college to do)...study to be a home inspector at someplace like the InterNachi... https://www.nachi.org/become-home-inspector.htmOnce you earn the badges you will know your stuff about SFH inspections.But still that's a big commitment and it's not needed to make money in this business...you can hire Home Inspectors, just like you can hire tax pros, bookkeeping, and etc...If you want to learn how to "put in cabinets", "replace a toilet", "shingle a roof", add a dormer, etc...you can learn on YouTube fast and easy.If you want to learn how to frame, get a job 9 to 5 with a framing contractor, and get ready to WORK HARD.Here is a 582 page picture book of how to build a house: https://www.amazon.com/Complete-Visual-Guide-Building-House/dp/1600850227Sit down next to a Keurig Machine with a book like this and your favorite mug and learn at your own pace.  

Purchased in 1978 and used until around 2013 when the drum literally wore out and started leaking and "Old Bessie" had to be retired. 

Main things mechanically and physically like roof age, furnace age and HWT age as well.

Otherwise, use your big heart, give discounts and when you get hit with a huge bill for a roof, plumbing, or furnace you will find your tenants don't give a crap about you even after you discounted their rent for several years.

We did a full cosmetic rehab, including new roof and HVAC.

Things like "roof failed - past useful life expectancy should replace".

@Sam Ohanesian I got a credit for the roof repair, so I’ll get that done.

Bush trimming and tree branch cutouts are included - if they are within 3-ft of the main property-structure (walls and roofs).Good luck.  

Little leaks will not be reported, slightly malfunctioning systems will not be noticed, you don't get to put your eyes on the property more than once or twice a year.

Call around and see what a basic service call costs for a variety of common issues: clogged toilet or sewer line, furnace or water heater pilot won't stay lit, garbage disposal is leaking, refrigerator isn't staying cold, etc.
