Debating putting our SFR up for sale in CO Springs.A few specs: SFR 3/2.5 and 2 car garage. 

The same house I bought, from the same builder, two blocks away is listed as a spec at $230 without any upgrades.

I am based in Seattle and want to learn more about the Portland market.Where do builders in PDX get construction loans for spec homes?  

Once you locate a builder show them your specs and plans and see what they offer.

Quick Specs: Built in 1968, 6 beds, 5 baths, 1 story in the front, halfway through the house there is a couple of rooms under ( I wouldn't consider it a basement).ARV: 1,300,000REPAIRS/RENOVATIONS: 350,000HOLDING COSTS 6MO: 54,000PURCHASE PRICE: 500,000Do the numbers look good?

Assuming the contractor is planning to provide:- Labor- Materials (including architectural shingles and similar gutter specs)- Tear off of existing roof and haul-away- Liability insurance- Workers comp insuranceThen I don't know where there can be much room for confusion on a bid. 

Just speaking from personal experience my partner and I are transitioning from custom home building to build and hold and spec sales with an eye on large scale development.  

Battery park which is east of Chamberlayne going up to Barton ave on both sides of Brookland park Blvd have seen rapid gentrification in the 2 years i have been there.

IN our market its VERY difficult to get spec loans but super simple to get rehab loans.Same terms here though 90% of cost... what will your 270k all in 1900 sq footers sell for... in our market they would go out at 350ish single level and 320 ish two story... that's suburbs of Portland inner city 500 to 600k We are building in Charleston and those exact dimensions will go for about 390 to 450 for those tall and skinnies... and all sell before they are done... like I said some days I like it some not so much...

I see new construction spec builders take months to move from one stage to the next while commercial buildings are framed and roofed sometimes in days. why the disparity?
