I wanted multifamily originally but found the lack of inventory and high prices a big obstacle.

Obviously new construction since that's the only way you can choose adjacent houses.We want to form a social connection by living next to each other, but don't want to be formally attached such as with an LLC etc.

I would just search up @Buildyourhideaway on any social media platform. 

Either the form is wrong or someone entered the wrong numbers or many socials got reported as one?    

Anna, you can also check out Youtube, Podcasts  and there numerous other Social Media platforms that also discuss this topic.

@Raj KandragulaRecommend 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.

the social safety net is well established and many investors on this site profit from it..

Your friend should work with then tenant to presure the Housing Authority to make a move as soon as possible, I am sure the tenant wanting to move in will want to presure his / her social worker to rapidly approve the place.

SinceI possess a social security number, and I am wondering if it is possible to open a new account remotely and online. 

I recommend that you expand your network and explore social media events for starters.
