I recently moved to Barcelona with my gf and two dogs and we are considering starting our real estate journey with our first investment property either in Barcelona or Valencia.

another issue it is about 18 months wait to get a Cabin started due to high demand for builder.  

But I'm looking over numbers and I'm starting to think it may have always been a bit of a unicorn that appeared once when the stars aligned, but otherwise doesn't really make sense under MOST conditions.I've nerded out a little and ran numbers comparing interest rates, P+I payments, and initial principal balances and I've found with MY assumptions, that the 1% rule is actually NEVER a valid filter. 

That way, they feel locked in while waiting for the rule to clear.Just communicate—if they really want the house, they’ll likely wait rather than start over.Good luck closing the deal!

You really need to decide on what is most important and then start looking. 

The learning curve for plumbing is a nightmare, you'll spend a lot of trips to the store and get frustrated starting over constantly. 

There is a lot of research to be done to make sure it is feasible before you start the project. 

@Chloe Salcedoi'd start with a house hack.

Be careful when you start thinking other sales will equate to the same numbers for your property. 

I'd feel comfortable investing ~$50k to start off.
