Let’s say it’s not assumable, what are my options without possibly going the seller financing route and not being able to refi it as planned due to some unforeseen legality? 

Trying to do both will in all likelihood not turn out well, with lots of unforeseen consequences.

Safest bet would be to let your Lender/servicer know of the unforeseen circumstances that came up so it doesn't look "sneaky" in the rare and unlikely event they would look into it further.

And even with a good crew it seems there are always delays and unforeseen (but hopefully not unplanned for) expenses.

If you’re already in a Fix & Flip project, but you need additional capital due to unforeseen circumstances how do you raise that money to complete a BRRRR that you already started.

We actually had our first rental property in Hawaii several years ago which we self managed but due to unforeseen circumstances we needed to sell it. 

And, yes def get on wholesalers lists.Finally, once you know the answers to these questions, then you buy at a discount to buffer any unforeseen problems or market conditions.

And while that may be true, that works for a 40 yr goal plan, but might not work for a shorter plan or unforeseen circumstances.

The only downside would be if the bank suddenly decided they aren't doing these anymore due to economic conditions or some other unforeseen circumstance. 

Good work.On budget.I am willing to concede TIME (hopefully within an acceptable deviation of forecast due to unforeseen issues on the work and NOT because the GC is pulling guys to another job)  for budget.
