Any local attorney that regularly practices in this area should be able to provide you with simple form contracts at minimal cost (this would take the attorney very little time).

This isn't a simple topic.  

There are literally hundreds of listings for this year.

Let's say I have 3 flats all renting out for $1.500, with a mortgage of each being around $500.000.That means I have to pay back $1.5m within 30 years.Now to keep it simple, that would mean I could pay back all monthly mortgages and still have about $300 profit on the side. 

I was thinking about assigning this to a fix n flipper considering this is literally a house right across from mine(thought it would be weird to sell it to my future neighbors).

A simple formula price you hope to sell it for times 70% minus yor fee gives you the moa max allowable offer

if you find one of these, the last known owner now owns the house again, free and clear. go to the register of deeds and records and GET A COPY OF THAT RELEASE OF LIEN". do some research and find that owner. chances are, they are living in some dingy dirty apartment really close by. i personally have done this 2 times. one house, i gave the owner $2000 for it and assumed the $3000 owed in back taxes. i sold that place 2 days later for an $8000 profit. the second house, i gave the owner $2250 for it and assumed $4700 in back taxes. i am currently rehabbing that place and will make a profit. if you find a house that the bank still owns, bring it to their attention. it may be literally sitting on someones desk, forgotten about. tell them that you want to purchase it right away before it becomes so delapidated that no one will make any money on it, including the bank. you might be surprised how fast they will work with you. get working, you have some homework to do....... good luck to you

I mean seriously, they'll bend you over.Don't just think property price is an indicator of C or D, literally go drive the neighborhoods your interested in, Friday night, party night, gets you a good feel for a neighborhood.If the neighborhood is having a party, that's a war zone.

it really depends on the circumstances.for instance if you just have one partner then a simple LLC agreement with you both as managing members works.. and then you take title int he name of the LLCif its your intent to get a large number of passive investors to fund these then you need to talk to securities attorney.. each state is different when it comes to these quasi partnerships.

This can be as simple as treating people kindly in your classes and getting to know them on a personal level.
