I've been using Skyline Steel from SW with Folkstone for the trim. 

General appreciation trends will be helpful, I'm sure.

@Jim K.Slides are steel though

They’ll show you what they earned last year so you can get a sense of what to expect, but be sure to look at revenue/ occupancy trends over time to see if the market is trending down post-2021 (and give their totals a haircut for your own forward looking projections if so).

I am mainly interested in buy and hold or rent by room using BRRRR strategies... numbers do seem to work if you are creative and what is positive is although big capital organizations have come in to Spain to invest, regular small/medium investors that actually use experienced info, strategies and network/community is not trending or arrived so strong as in overseas.Cheers!

I see nothing in what you posted that trends positive.

These are the zips we focus on and new construction trends we focus on and the prices housing units are going for here.

Sometimes you can tell because of rust staining and buildup on the outside of such affected pipes,   but even without that they can be weakened considerably from their original state.On the drain side galvanized branch drains  (1.25 through 2" galvanized pipes)  can also rust out or clog up as the rust on the inside is very rough and catches hair, grease,  and other debris and will eventually need aggressive rootering,   which if the pipes have rusted enough may open up holes in them.I should note CAST IRON (hub and bell) old sewer pipe,  at least the 3" and 4" stuff seems to have a bit longer lifespan than galvanized steel;  it still rusts but doesn't crumble and flake and encourage blockages like steel does,   so an old house with a cast 4" sewer stack you may be fine for many decades more if you just replace all the branch lines going into it but leave the main stack.   

Develop skills like sales and negotiation, stay updated with market trends, and plan your career through mentorship and interests.Good luck!
