I plan to use platforms like Airbnb, VRBO, etc to market and rent the property.Will I still be able to write off the expenses associated with the remodel if it is purchased as a second home??

If any of your neighbors report you, Airbnb will boot you off the platform. 

Airbnb seems to be the best platform to get those renters but it doesn't seem that compatible with the landlord/tenant law complexities that kick in after 30 days. 

VRBO is also a platform you should use.

Isabela is correct, rather than jumping from one real estate marketing platform to another, make sure you're rental is accurately priced, professional photos are displayed appropriately, and the description is thorough and informative.

Or it could stay a dump for 40 years and you lose everything.There's calculated risk, and then there's foolish gambling.

You can browse other San Diego spaces on the platform to get an idea and inspo!

Nationally there are several hundreds different MLS systems and more than a handful of different platforms. 

Providing an educational platform is providing an opportunity to people and like I said in some cases, some of them will choose to invest with you.

If I love my job, but want to leave a legacy and want to put my money somewhere else besides the Wall Street Gambling Casino, it would be Appreciation.
