You typically need to frame the vents in.4) Hardwood costs seems low but maybe you are only doing a small rooms worth5) Counter top installation is a bit off in my guess but maybe you have a small easy kitchen6) Appliance installation is usually carried out by the vendor you bought it from and it is not usually 10007) Door knobs seems a bit low unless you are only doing a few8) Backsplach material seems low as wellOutput is visually fine but I have many questions about inputs and if they are off then your outputs will be off as wel1) IRR looks suspect as well.

Also, here is a thread you may want to follow as it will be a good visual step-by-step lesson. https://www.biggerpockets.com/forums/48/topics/259...

90% of the time you can see the plumbing issues with visual inspection.

Personally, I do worry about shingle color, because depending on the roof pitch and size relative to the rest of the house, it will have 30% to 60% of the visual impact when you first look at it.I have replaced shingles more than once just because I couldn't make the existing color style work with the rest of the house.They look like a dimensional/architectural shingle from the picture (not a cheap 3 tab still used in our area).

Spend several days visualizing the entire process and writing out a complete list of tasks.

@David Dachtera - We're in contact with the interested buyer's agent and trying to persuade to be #1.We have had a few comment about wanting a pool, so we are having our pool builder sketch up a couple of pool renderings to show what would fit and a potential layout/visual for those interested.

.#2, Is the fact that people who are not landlords have a hard time visualizing what the place will look like once it has been repainted, new carpeting, and ready for show.  

I just went to Barnes and Noble and picked up the book "architectural's in visuals" and it seems to answer my request but if you have any other books that you would recommend, I will look into those as well.Lastly, I forgot to mention this as well.

I call them Safety and Water Inspections, check all the smoke alarms and under every sink, this gets me a visual of pretty much the entire property.

New CabinetsAnything else should cost less than $2000, and even items 3-6 above should be less than $3500.So, learn how to visually inspect the roof and learn how to identify structural issues, and any additional surprises really shouldn't hurt you too much, even if you under-estimated the repairs.Of course, if you ever had any major concerns about structural issues, hire a structural engineer for $300, and if you have any questions about the roof, you can generally get a roof inspection from a roofing contractor for free.
