I'd rather have a large margin/buffer for error when calculating these rehab costs.The current process I am using:* Using realtor or Zillow to find properties * Running through the rental calculator and making a spreadsheet to track* Leveraging this video and deck as my starting point: https://biggerpockets.s3.amazo...

While there may not be a large profit margin, there is not much to do to the property.Here are the details:Del City, OK Area (Oklahoma City, OK)1 Bed; 1 Bath840 Sq Ft on 0.38 AcreCentral Heat/AirWhole house pre-plumbedCount Assessed Value = $58,000Zillow's Estimated Value = $66,700The roof has a new deck, and it needs to be shingled, but he already has the shingles on site.

The house is 3/3,2016 sqft, built in 2017, large fenced in backyard with deck.

The deck is stacked and the majority owner holds too much power to tank the property if they go under.  

Maybe a combo of Venezuela and Blade Runner!

For instance I will be heading up soon to change out a deck railing to an updated style.  

Next will be a deck in the back and fixing the garage.

Can I use closed cell foam directly on the decking and joists?

Also, many homeowners take great pride in their yards and gardens as well as keeping up with general exterior upkeep such as painting or staining fences and decks. 

Grading / foundation I need done, frame the garage walls onsite, deck / stairs onsite, then stitch the boxes is how I see it.
