they have different cost structure, where usually the ones with lower % will charge you more for placement fee on the tenants and stuff. 

In a nut shell, choose a market, find a local partner you trust and pull the trigger!

The way I read it, all unit owners are being assessed to fix a structural issue affecting two of three buildings. 

I have a really great property in Westchester, NY it is 3unit plus basement multi-family building but structured as Apartment that has 12room 3.5 beats in the kitchen...finished 2bd 1b basement w/h are all occupied with tenants who have been living there for years(5,4,3..) and pay on time.

So I need to come up with roughly $90K to close the deal.I have 401K funds that come available penalty-free in 1 1/2 years to cover all options.What are my options and how would I structure them?  

I was wondering if anyone could point in the directions of book(s), website(s) (beside just BP) or other resources where I can learn the art of structuring deals.I really want to learn two sides to structuring deals:1) Investors: How to learn the various ways to structure real estate days that will capture a potential investors interest. 2) Purchasing: How to learn the various ways to structure real estate deals that i am interested in purchasing but learning how to put it together so its not just a win for myself and my investors but also the seller. 

The buyer puts a 3% earnest money into escrow, the buyer has an inspection contingency period inspect 7-12days depending on house and structure of your offer, loan contingency period 10-17 days depending on lender and speed. 3-4 days before closing you and your clients do a final walk-through of the house.

For example in the city I live there are no rental licenses, electrical permits are through the state, and the city requires permits for plumbing and structural building changes. 

So I am looking for suggestions on a fair way to structure such a partnership, or is the only way to do it, to have him get 50% of the profits, while me and the other guy get 25% each? 

My first questions to get answered are always:-  Do they have an existing mortgage or do they own the home free and clear (if a mortgage is present, do they need to pay it off for the deal to work)- Do they need the cash or do they want a prolonged income streamAnswers to those questions can help understand some of the key seller motivations.A typical seller financing structure would have a down-payment that would range from $10-$20K up to 10%-20%.Interest rates typically range 1-4pts over residential real estate mortgage interest ratesIf the seller wants long term cash-flow, the term can be 10yr-30yr.
