At least in Florida, all you need to get a real estate license is to be 18 years of age, have a high school degree or equivalency, a social security number, pass a background check (murders are not allowed, embezzlement is frowned upon as are sexual offenses against children and elders; most other offenses require 'extensive review'), and pass a licensing exam that prepares the newbie for nothing - and the pass rate is 46%. 

I negotiated a contract extension.

This involves extensive dirt grading work and retaining walls (with railings sometimes) which together are very expensive.

As things come up that the lease doesn’t cover, I end up modifying things for the next tenant or on lease extensions.  

Hi everyone,I’m a professional real estate developer based in Central Florida near Orlando.Background: licensed architect with deep experience in residential subdivisions, underwriting, entitlements, building permits, construction management, and maintaining extensive contacts with national home builders.My specialization is converting raw land into paper or finished home lots for sale to national and regional home builders.

That accounts for overages and timeline extensions.

6) ExteriorFlower beds look great for curb appeal, but tenants rarely take care of them.Downspout extensions will be stepped on, bike-riden over, etc.

Option #3 you provided - offering a concession such as a lease extension or upgrades to the house in exchange for new lease terms.

It's a combination now, but the biggest killer is labor costs and timeline extension.

So, once the counter party (investor) indicates a buy decision has been made, the sponsor stops providing information other than what’s in the PPM.We try to schedule hour long conversations with new investors, but many cut it short claiming extensive expertise in real estate in general and syndications/funds in particular.
