Additionally, the dollar(the primary currency) is used there and the prices are CHEAP compared to US, across the spectrum - not just in Real Estate.

If that were in place,   it would not affect the screening criteria,  except that you would have to track the order that applicants filed (following a complex bureaucratic process of course) and process them in order,  including granting appeals, accomodations (for example for non-english speakers) and re-evaluations that could take days.I'm sure there are more details I'm missing,  but thats the broad strokes.     

There's a spectrum between the two, but if you've got a well-paying job you're probably best advised to keep that and build up funds to investing with.

If they have an option to renew and are not in violation of the lease then unless you have broad language in the lease for landlords rights you might run into big problems.Before you approach the tenant with your thoughts it might be beneficial to have a local commercial attorney review your lease and all addendums and  give you their thoughts as to how to proceed. 

For broad based return I multiply the P&I income by 12 months then divide by my desired return.

I think having very broad deliverables in writing can spur along action (unless you were splitting holding costs for this very reason) and help keep the contractor on task.  

Let's say I had $200,000 to invest (200 being the median in my area), and I decided to buy two, $100k SFDs instead of one $200k one. Is that a decent idea if you can get the same or more rent by doing it that way? Or ...

For that matter, its a broad term.

. , I don't have any experience w/ this either, but I was thinking about the opposite end of the spectrum; least likely to be redeemed, highest interest if it is, dirt cheap property if it's not.@ .25% isn't it better just to open a savings account?

But we will see what develops when we negotiate.Part of the problem is that there is so little in writing, and it's such a small town that it would make life very uncomfortable to have any kind of legal proceedings going on to get our money back, and yes, we are planning on living here at least for the next year.So I need to have a Purchase Agreement drawn up, with some purposefully broad contingency clauses (such as "Subject to Buyer Inspection" and "Down Payment shall be refundable if Buyer chooses not to purchase" etc).I'm mostly trying to figure out how to structure the paperwork right now to give myself the most protection during the buying process and some legal standing RE our $25k deposit, and also how to turn this into a win for both he and I.
