If you are new to REI as a whole, I would say that you should continue getting educated.

3) Will I continue paying same property tax on primary and new assessed property tax on the "new" ADU ?

I always wanted to ask her why she felt like a couple of months of construction was worse than continuing to let the home be a drug house and neighborhood eyesore...

Depending on tenant type you are marketing to (national, regional, mom and pop), how much new development is ongoing versus existing vacant space, and box size type will play into how long it takes to lease a space and get rent going.

Once I sold the collateral at auction to take it over he continued to threaten and intimidate the tenants to pay him rent.

Hi Matt,I used to play poker professionally and trading in the past.

Tell him you are sorry but you can not continue to cover your expenses if rent is not at $2200.Money is more valuable than tenant friends.

Most other brokerages I spoke with had additional recurring fees on top of the above minimum costs.As far as commission splits I'm not sure what I can publicly share so I'll play it safe and just say that its similar to what KW offered but without the recurring fees and can be negotiable and go up over time.

So I am starting out, and these are the two scenarios that are playing out:1) Three family with renters already but these properties are going for around 400k, almost 150k above there assessment value. 

If you are dealing with partners, I would highly suggest creating an LLC entity AND have it include a an operating agreement that covers who does what and how you will eventually dissolve the company/dispose of the property.Disclaimer: I am not an attorney nor do I play one on the internet.
