Quote from @Sofia Komrskova: Don't spend that kind of money on courses.

Sellers rarely mind the low deposit and extended closing period due to the nature of the property, or at least they can be made aware of the fact that their lot has issues that will take MY time and MY money to solve and then they come around.My terms on the flip are: Minimum 10K spread between purchase and flip value.  1-2K deposit upfront to hold the property for 7 days then the deposit becomes non-refundable after the 7th day and the buyer has the same amount of time that I originally negotiated with seller typically 8-12 months(its a purchase contract but because of contingencies its essentially an option).  

I just set up my vrbo account and still some finer details about planning the communication, cleaning service, maintenance persons, etc…

And I will always be against delaying the receipt of money.

We then use our money for the improvements.

Again, this is a conversation to have with your accountant to ensure the benefits would outweigh the costs.Another misconception is that there is little value in a cost segregation study for properties that do not have a lot of personal property in them or very little interior build out, such as industrial warehouses.

I've used the search feature on this forum but didn't have much luck.Are there any US investors, hard money lenders, or groups that invest in flips outside of the United States, specifically in Europe (Netherlands, Spain, etc.)?

There are so many online hard money lenders.

What appears to be great "curb appeal" to one person might be overwhelming to another. 

You should take a job for the education and not the money.
