Where the roof leaked and was patched you also need to look in the crawl space and make sure there is no rot or mold on the beams between the ceiling and the roof. 

I have done  major renovation (no such think as basic fix up for a Victorian) on a dozen Historic homes, that had all been bypassed by other investors.You're dealing with +100 years of various owners patching over problems.

My estimate is based on the following: New carpet/pad (900') 1 new interior door 1 new exterior door 1 screen door Yard clean Fence fix 2 stucco patch areas painted to match Complete interior paint Misc minor things like interior door knobs, outlet covers, bathroom fixts etc.I plan to pay for a home inspection and if any defects are found that would affect resale I intend ask the seller for concessions on these.

A contractor doesn't want to big on a drywall patch.

However, I was finally able to go in and fix all of the cob job patches the old landlord did.  

I need slightly urgent advice.I placed an offer on a house last week, and now I've had the inspector in as well as one of several contractors to get estimate for needed stuff.I got a great price on the offer I think, the inspector is also a structural engineer and he said he thought it was a great investment property.Issues include:-mold-basement moisture-main roof OK, but some patches needed-front porch roof & detached garage need replacing-boiler bearning bad-radon (4.6)That's all before interior fixes like plaster (from all the roof leaks), new carpets and interior painting.This is my first deal, and while I'm not afraid of all the work involved, The estimates are getting close to my bottom line number.I'm starting to get nervous that the rehab costs will make this unworkable...and I really want it to work.I have been an excel spreadsheet (Property Analysis Buy & Hold) and have plugged in a LOT of numbers, including a rehab number up to 40,000...and the property still gives me a 5% Cash on Cash return, which isn't bad, and a cash flow of anywhere from $100/month for lowball rents to up to $1000+ cash flow for top number rents inline with the area for a nice place.The advice I'm looking for is how to figure my bottom line offer.

It looks like it will take about 150k to bring it up to its full glory and probably about 75k to patch and paint.

Joel,it all depends on how much stretching is required, most of the time I had to do patch up work along with stretching but I would say I paid close to 150-200$ for streching an 1200 sqft place generally.I have a guy who does a great job with carpet stretching and fix ups PM me if you need his contact info.

Forgot the roof was just a patch job that he said he was going to do.

We have tried multiple strategies to get our patching done.
