Pensioners will also need to look in to healthcare contingency plans as an alternative to any reciprocal agreements that aren’t continued.The best case scenario is that Spain introduces new rules providing British property buyers and expats with similar rights to those that we enjoy currently as EU citizens, so, in this instance, nothing really changes.The other more unlikely scenario would be for the UK to adopt a similar stance to Norway and join the EEA, providing what are essentially the same automatic rights to buy a home, work and reside within EU countries that exist now.

If not, then as @Joe Splitrock said you may want to look at an alternative investment.

Situations of this nature usually happen as a combination of what the tenant and landlord have done or failed to do during the course of the relationship.

Any alternative methods to get all three owners an equity stake?

If you can scoop up 190k of tax free gains (an option only available if it was your primary at least 2 of the last 5 years) that you can deploy doing some HML at 8-10%/year, that seems to br the clear winner vs the alternative of earning less than 1%.Your cash on cash should be calculated as annual income divided by original cash outlay plus current equity.

They have access to alternative transfer sources and can assist with the advice and guidance you'd need.

No - this is not my first 'rodeo' but this case is a bit outrageous:  Here are the details:1) House listed as "gas" (= natural gas; not propane; houses w/ propane are listed as such).

I would imagine that the details of how builders structure partnerships vary based on the specific nature of the deal and the parties involved (how extensive is each person's track record, how much money will the investor be expected to invest, how much money are you willing and able to invest to show "skin in the game", etc.). 

The alternative would be to refinance into a conventional loan, which would have a lower seasoning period but also a lower maximum LTV rate as well.What are your thoughts on these solutions.

Alternatively, you can get the house and offer cash for keys for the tenant to move.
