Both of these water leaks damaged the kitchen base cabinets (brand new and installed in Aug 2017) resulting in moldly cabinets along the inside bases, damaged water resistance vinyl laminate floors in kitchen, damage to living room wood laminate floors, and a bedroom with moldy carpet due to leak from the the hole in bath tub.  

Morning BiggerPockets world.I am currently on the first R and trying to plan my renovation in a way that maximizes my appraisal ( as expected)...I have the opportunity to save about a grand on my rehab by having a used HVAC system installed. 

Then create a patio/entry for each lower unit by a simple screen of an above-ground planter from the post to the stairs, or maybe at an angle to where the stairs begin.The rest is comparatively very simple... don't paint the brick, do the siding in a darker dusty green, the window muntins in a very dark gray (it'll match the black powder-coated hog wire balusters), get a very LARGE round fake attic vent for the gable,https://cdn.shopify.com/s/files/1/2196/8707/produc...and install a clete at the bottom of the gable which will look like a horizontal supporting member for the second-story columns.Lose those shutters, paint the entry doors a very deep, rich color, with the first and second story doors slightly different.

You can find them for around $350ish an they are easy to install.  

Also make sure the installation is done correctly.

The house that i am looking into buying is in centerpoint alabama and purchase price at $100k.The major concern that i am having are:The roof is at end of life.floor joist needs to be install due to flooring bad deflectionThere are broken cement at the patio / deckPossible water leak to the basement walls.i just don’t want to be the person who ends up with the expenses the previous owner should be taking care of.Can you give an advice on how to deal with this property?

It doesn't take a lot for a project to go 150-200K over budget when the building department holds you up, the gas company can't install new lines for 6 months, and your subs walk off the job. 

I have been told that this can very difficult and costly to do due to opening walls/ceilings.(2) Install a mini split system (outside condenser and wall units) for the second and third floor.  

The current owner 'pays' for water and I want to sub-meter and save on those costs while I hold the property long term.I've had one company tell me they do no less than 12 installations and other have not returned my calls. 

Putting floors in first will make the installation quicker and easier.
