I would not accept until and unless I see evidence of cosigner's financial status in their home country. 

Up until the trustee sale (foreclosure auction), the home is still owned and fully controlled by the home owner.I’m assuming you’re going to be looking at off-market properties (since loan status isn’t something they advertise on the MLS so you likely wouldn’t even know if it was in default if it’s a listed property).So, in that case, you’d just negotiate a purchase agreement with the home owner and then take the contract to your local escrow/title company to open escrow. 

They are advertising quite a bit on social media.

but then we run into the "Socialism" idealists who think if we do anything that is Government related to address health care, then they, the Government is taking control of our country??

@Eddie TorresI like letters but we’re definitely not allowed to mention familial status (California).  

Especially when you consider REP status from STR management. 

1) Communicating with property mangers on tenant issues, vacancies, etc. 2) Listening to/Attending Webinars regarding real estate investing3) Driving for dollars4) Searching MLS and online for on-market deals5) Working on the business's social media accounts 6) Posting and reading through real estate forums (Such as this one) for real estate purposes (finding deals, educational purposes, etc.)

@Cliff ConnorRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Of course, if the reporting tenant is overly sensitive or has unrealistic expectations of social interaction, then the credibility of the report may be low. 

@Becca F. if you add an ADU in San Francisco you change the status of the SFH to a 2 unit building, and then you’re definitely under rent control.
