@Alexander Felice - While not a "protected class" per se, people do have a right to keep and bear arms under the 2nd amendment, particularly in their domicile, and I would caution against infringing on a tenant's constitutional rights.

My TOTAL objection is, HUD messes with my contract and property management, not individuals per se. 

If you can't find a "mentor" per se, definitely find a few people in the industry to shadow, at the minimum.  

Etc.For your info, here's a California Dept of Consumer Affairs website that covers security deposit info, and what's considered damage vs. normal wear and tear:http://www.dca.ca.gov/publications/landlordbook/se...

Well I put 6k down last year for my wife's anniversary present. 2014 Toyota Camry SE loaded.Payment isn't much only the high 200's monthly after down payment.Had old cars paid off for years and years.

If they fight you on it, you would have to return their entire deposit, regardless of any damage.http://www.dca.ca.gov/publications/landlordbook/se...Scroll down to the blue section. 

Be sure you include the receipts, including the receipt for the toilet blockage.Then, if they decide to sue you over their deposit, you should be in good shape.Read especially the blue section regarding initial inspections:http://www.dca.ca.gov/publications/landlordbook/se...

Scroll down to the blue section, toward the bottom of that section on useful life and normal wear and tear:http://www.dca.ca.gov/publications/landlordbook/se...

If that money is left in the business at the end of each year is it subject to se tax.

Primarily looking in East, S/E, So.
