First, let's examine your initial post.  

Rates weren't quite as good, longer periods before payoff was allowed (defeasance penalties could be very high), and the nerve-wracking nature of not knowing until you close whether the loan is going through - not sure if that's for all loans, but we didn't know for certain until the day before closing.

Again, others might feel differently here.3) property level due diligence: (takes seconds to weeks per deal): here is where I drill in with the low-level details.a) pro forma popping: I examine all the assumptions, and see if they are overoptimistic or not.

Most people who live in parks these days cannot afford to buy and move a home and there is no lending out there they can qualify for.In the vast majority of cases the idea of building a park starts to look worse and worse the more you examine it.  

And looks like next door sold for 350k and it was new construction...again all things need to be considered as your buyers will consider them.Oh... you hit a nerve on this one :-)Across the street was not new construction.

Took about an hour.After getting up enough nerve (took about 2 hours), I called him.

You may have miscalculated the offer amount and insulted the seller on a property that may actually be worth more once you examine it more carefully.If you are wanting to absolutely minimize any possible interaction with un-motivated sellers then you can certainly spend the extra time to research the property values up front and make hard offers with dollar amounts.

Alan, I would recommend attending a local investor group such as RIREIG or Black Diamond REI and asking some members there.It also depends on what you mean by "back to back closings".If you mean one closing after another in general, that's nothing special - there's no difference between having closings at 1pm and 2pm vs. 1pm and 5pm.If you mean that the first buyer doesn't need to bring money to the first closing because s/he is actually using funds from the second closing in the first closing, it's difficult to find an attorney who will do that these days.Like a lot of things, this is fallout from the financial crisis of 2008-2009 which resulted in things such as the Dodd-Frank regulation.Cleaning up after bad actors resulted in a lot of examination of closing and mortgage practices, such as The Detection and Deterrence of Mortgage Fraud Against Financial Institutions: A White Paper (2009).There are a lot of issues here and you might be best establishing a relationship with an experienced real estate attorney as an advisor in general (again, ask around at local investment groups), and then broaching the question of double closings.In general an assignment is far, far preferable to a double closing.

If you are carrying a house and vehicle debt that makes health insurance cost prohibitive, maybe you should be re-examining your priorities.
