That's where bad experience/nightmare come in.Lastly, to answer your question, to build a basically designed, square/rectangular house without crazy jigsaw puzzled cuts on roof, the following price is a good competitive construction only price for what you need to do:Around $165 per sq ft on conditioned space (for an average 1200 to 1800 sq ft house, 8-9ft high ceiling, everything is investor grade finishes), $90-100 per sq ft for garages/unconditioned storage, $60 per sq ft for porches/opened spaces.  

@Sharma Parth  With your total cost ceiling of $120K, paired with the objective of completing a BRRRR you are setting yourself up for failure.

I'm going to be painting the walls and ceilings next, but I am unsure what to do with the trim and doors.

Two bedrooms in that size especially with a basement which probably has lower ceilings and not a lot of windows will look more like a prison cell/

you don't want to lower your glass ceiling so to speak.  

We have been in the Smokies a long time, and many guest accidents, some of them life threatening over the years, could have been avoided with an annual risk management walk-thru:- Loose or rotting steps- Nails poking up through deck boards- Stinging insect hives or infestations- Ceiling fans that are barely hanging on- Loose deck, stair, and landing railings- And oh, about a hundred other things!

Floor to ceiling windows in the front.

a dozen or more times.Bad surprises - The basement flooded, which meant water got into and messed up the furnace in late December, crazy rain and windstorms meant water getting through the new roof and leaking into the ceilings, a family of skunks found their way underneath the house, joists in the basement were cut out for a water line, which needed some structural repair before the bathroom could be completed.  

New RVP flooring and painting walls, trim, and ceilings are also included in this cost.Deck additionWith space to enjoy the great outdoors continuing to be high on home-hunters’ wishlists, a deck addition is a great investment, even if you plan on selling soon.

And if your architect is designing you this house with 8 ft ceilings, FIRE HIM NOW.
