It could be anything... a mistake in estimating, a cost overrun, or something like the place burns down and the insurance wasn't properly taken out, or theft (of the money outright) or theft of materials along the way.    

However, I'm unsure about the costs of maintaining the SL in Spain, especially cause I read in some forums that these costs can be pricey..Do you have any views on the above based on your experience?

First question would be: what is the cost per kwh vs cost per gal of LPG?

@Cameron Porter ultimately the most important part is the ARV, inclusive of the expected rehab costs.

Or if you want a lower monthly payment, then do the 20% down.You can also negotiate credits with the sellers to use towards your closing costs or rate buy down.

Many months of costly vacancy, local market rent & resale deteriation, special assessments, property taxes and maintanance fees suggest a quick sale would have been the wise thing to do 2 years ago.

Would the value of the remodel increase the rents or the selling price that would out weight the cost? 

This allowed our partner, Jamari Sprueil, to move forward without any upfront costs.

I am estimating the note would cost 2.5k per month at most. 

The very tragic LA fires have generated a lot of discussion about insurance costs.
