You have to provide a zoning disclosure now as part of your leases, and failure to do so is grounds for a misdemeanor.  

It's the single biggest failure point for so many investors, in my opinion, because  without it we're just dogs chasing our tail.

Mechanical and electrical permits.

For example, If someone hates socialism, they can point to Cuba and Venezuela as examples of its failures.

Also consider Condition of roof and mechanicals in your capex/maintenance  allowance. replacing 2 boilers (or hvac), 2 hot water heaters, and a roof within a short timeframe can hurt (speaking from personal experience :)

Failure to do so only delays the response time, or you may not get one at all.

Common failures are for peeling paint, cracked windows, loose handrails, crumbly cement steps - and all of this applies even to out buildings like sheds. 

I all ways fix all mechanical  issues  on all rentals .Fact I do stuff that some  flippers on here would not do .Hot water tank that is over 10 year old I change it out .Now my labor cost is very friendly same plumber for 30 years .HVAC units, I will not leave  a run out sled on a rental and hope for the best .I am a long term holder so it makes sense .

So, in order to have some mechanical control over market risk we can improve the location, improve the vintage, or improve the asset.

I’ve been researching the market aswel as I am a recent mechanical engineering graduate of UF.
