Example for my market: - water heater $1600 (lower end of licensed plumber cost), 12.5 years (150 months) $10.67/month- roof (asphalt shingle) 2 br, 2ba typical size ~$10k licensed, 20 year life span $41.67/monthkitchen, exterior paint, flooring, plumbing, electrical, fencing, tree trimming (I have a property where the tree trimming is one of the larger maintenance/cap ex items at over $1k/year), bathrooms.  

Once your earnings level off, or you're exhausted from continuously pounding the pavement, then kick back and enjoy (and save) your income streams that you've worked hard to build.

The road is getting pave with asphalt and the house is on a well.

Panels can be lifted up by hand, the ridge caps aren't actually ridge caps but someone bent metal pieces to DIY a ridge cap, the roof isn't vented, and no underlayment between the asphalt shingles and metal roof. 

In the middle of the summer if you go out an hour or two after dark in the city it is one temp and you can feel the heat radiating off of the block walls and asphalt streets still.

When this house here was first built, we closed in mid-March before sod and asphalt were available to be laid, though the sidewalk was done, but the front walk from the driveway to the house was not.

The roof was so old that most asphalt shingles were down to just the base fiberglass base material.  

Your lender will require this for major expenses like roofing, asphalt, hvac, appliances, etc.Rehab costs would be if the property needs work when you purchase.

I have a friend who's done it a few times, but for the most part it's pretty tough because it's hard to find the best deals unless you're here to pound the pavement.

Check the condition of the roof, siding, windows, pavement, lawn, deck, porch, driveway, garage door.....walls, floors, light fixtures, switches, outlets, furnace, AC, pipes, stairs...
