if yes then you got the answer, an appraiser will never come in with the proper value of A turnkey, because they rely on local comps even though those comps need much work and the principal is already done and cash flowing.2- These turnkey sellers usually purchase there properties for far below market value, if this is the case the appraiser might appraise for A lower amount due to the previous sale on the property.I don't know what turnkey seller specifically you are talking about of, but if their customers are happy then you got your answer, if their customers claim they were ripped of then you got the answer as well.

Most foreign buyers are high net worth individuals who want to park their money there in a safe haven and they don't need BP.No restrictions apply to American buyers in the countries they'd generally want to buy, including those mentioned by Federico and many other popular countries.When it comes to Spain specifically, some more conservative banks will ask you for a 40% downpayment (that would be the maximum) but that isn't the rule.

ALSO, I have not had to do an eviction following a partial payment agreement (so I don't know exactly how that would pan out in our courts), all of my tenants have so far completed their payment agreements as signed.Multifamily Northwest has forms for these types of things available via the Rental Forms Center at https://rentalformscenter.com/ Their forms are typically well reviewed by local attorneys; as you'll note, on the Partial Rent Payment Receipt there is verbiage specifically about if the landlord has/has not served a termination notice and reserving the landlords right to eviction if the agreement is not completed. 

@Brandon Shapiro what specifically do people say about these groups?

I never go off of a flat percentage on anything, I analyze the costs to get to a specific return I target and analyze the risk that is involved. 70% may be an initial metric to see if it is even worth pursuing, but every deal should be evaluated independently based on costs, time and risk involved.

Are there specific reasons you don't want to rent them out (e.g. bad previous experience with a tenant)? 

They can evaluate your specific case and guide you through the process effectively

One of my first questions is always - "what are your specific goals?"

I mean in general what sort of expert should I try finding first, but if someone has specific people in mind who deal with the UP that works for me too.

For us, the only time we pay contractors upfront is when it is for really specific jobs like full HVAC and full Electrical jobs, and these are somewhat large companies with vans and trucks, so we know that these guys aren't running anywhere with our $3k upfront payment.
