You don't want an owner taking away time and energy from other owners who would have committed to you as a buyer.It's a  cat and mouse game and sometimes you win and sometimes you lose but there are more properties in the future on the market and off the market to consider.

Just make sure this is not the case before you pursue a lot of time and energy in to filing a complaint. 

This is going to be a bit of a tough love reply...if you want to invest in real estate long-term or own more than a unit or two, you are not going to want to dedicate your time and energy (and money) debating about whether or not to paint walls that don't need it. 

HVAC unit or two goes out, multiple units become vacant at once, economic downturn, etc.100% financing is not problematic, with reserves...

I am going to start a significant remodel of my house in Santa Monica and wanted to maximize all possible rebates, grants or energy rebates that are available for new roofs, windows, appliances, insulation, landscaping..ect.I have a basic list (local municipality and appliance rebates) but didn't know if there was anything that I was missing or didn't know about...possibly other agencies?

We have wanted to invest in real estate for quite some time but never had the time, energy, or money to do so.  

Of course there are some good podcasts that cover real estate, finance and economics that you find helpful.  

So my only fear would be having the 10 years come due right in the middle of a major economic crisis when little to no money is available for refi.

I would add vinyl plank flooring, energy effiecent fixtures (led bulbs,low flow shower heads, water saver toilets.)

If you go further inland, you run into economically depressed areas.
