I am re-structuring my wholesale business and I’m wanting to find a closing attorney to develop an ongoing business relationship with to handle all of my double closings in Washington state.

Unfortunately you will have to spend money to defend but in some cases you can recoup legal fees if you prevail and the suit is baseless.The key is to make sure that you know what your doing first and foremost, Structure your deals correctly and provide proper, complete and thorough disclosures.

When building up you may need to reinforce the structure below to accommodate the additional weight.

Granted, you still need to conduct due diligence on the underlying asset, the operator/partner that you end up working with and the deal structure that is purposed to hold the investment.  

I was wondering how I could structure the deal so I could do something like use FHA(or if there is a better option all together than FHA) for the first four units and seller finance, or use other loan vehicle, for the remaining units. 

If you have a property management software some of those have built in online payment structures you can set up. 

You can only structure a 1031 Exchange on properties held for rental, investment or business use (not personal use).  

Also, find out whether they should be instructed to stay out of the property or if it’s safe to enter (structural issues?)

The real interest rate of these products can go to as high as 20% but the loans are structured in such a complicated way that, sadly, most people don't realize that until it's too late.The alternative to bank financing is seller financing.

Once you learn experientially, then I think it would be good to gradually move into more complex deals (off-market, complex financing structures, in need of large repairs, etc).
