dogsbite.org is a propagandist site created by a web designer who was bitten by a dog.

I'm considering purchasing a condo or a small SFH in the Oceanside/Carlsbad area as an investment property and renting it out on a short term rental site like AirBNB. 

Just like the BRRR that is talked about on this site.. shoot we were doing those 30 years ago.. we just called it cash out refi.. so you take someone who just brands it and folks think is some great idea that was just created..  

If you are using a third-party site to conduct the background checks, sometimes they have the option to send a person, a denial letter, and due to the fair credit act it may be required to send them a notice, informing them that you checked their credit and background so that they have a receipt that it was completed.

I use DealMachine, and I'm happy with it (I read the instructions you provide at the site, so I actually wasn't surprised by anything).

I love this site and all the professionals that give away free advice with no strings attached.

Check Better business bureau  site for reviews and so many complaints.

Found this property through our local online foreclosure auction site.

No, DIY is not the same as a virtual site visit or a study done by engineers @Dana YobstAs @V.G Jason said, you could very likely cost yourself more in time and money.

A good place to get an idea of what they look like is to go to one of the crowdfunding sites.
