Some come a facet, others don't, just shop around.If you DIY the install you'll save more money.

If not, that work will likely come due later if it wasn't done in compliance or off of YouTube.Flipping right now is very hard, and much harder as a first-timer trying to DIY it with low inventory.

I asked her to get it installed.  

I’m waiting on a contractor to come install an egress anyways, so the extra month it’s taking me to do minor repairs and paint  hasnt affected the schedule yet, but it’s definitely an important lesson.

I would have required that a professional install it.

After moving out, we re-stained the front porch posts with a darker stain (photo is pre-stain), replaced the front door, did touch-up painting on walls and trim, installed new keyed-alike locks on front/back door, and installed a vented bathroom exhaust fan that wasn't there prior. 

I had them installed during the remodel up there.The first floor where my wife and I currently occupy is also recently updated with a new kitchen, all new appliances and is also a 2 bedroom with a fully finished basement.

HVAC duct work insulation is also deteriorated.No vapor barriers installed eitherSome fungi/mold growth notedPlumbingMultiple small leaks under sinks and from bathtub and toilets.House has Polybutylene plastic plumbing which is dangerousMain shut off valve is damagedElecticalSome small exposed wiring and bad splicing.Whole house has no GFCI's or grounding outletsInteriorMoisture spots on ceilingExteriorLose Vinyl SidingDoor Jams and Window trim have moisture damageDriveway need replacementRoofingMinor leaks noted in atticRecommended to replace roof covering, but not whole roofSome fungi growth noted in roofSo some of the question I am trying to tackle with this work is:How much should I budget for the main issues listed? 

Keep in mind, you will likely have to install a sprinkler system, among making other changes for the home to be used for that purpose.

I've seen situations where people tried to cut corners with cheaper software or DIY options, only to face costly IRS issues later.
