As for your out-of-pocket costs, it really depends on the property and your specific situation, but budgeting around 5-10% of the purchase price for these extras is a good starting point.

Depends on where you are. 

And/or are you willing to go through a potentially more rigorous underwrite to get better terms (possibility, depending on what you've got on your end). 

You can buy a new one brand name for around 300-700 dollars, depending on brand, and get it installed for $200, or do it yourself with some basic skills and youtube video.

It all depends upon how long you can wait.  

It depends on the property, of course.

Ripping out a bathroom for 5-10k depending on your contractor connections or personal skills doesn't seem like a good pay off for a rental so I look for creative solutions for working with what we have...There is prob no exhaust fan system so you either need to keep the window or install exhaust fan system.

If you are asking what the cost of rehab is, well that depends on the condition.

I am a builder in the area and you can make at least twice as much depending on the area of Charleston you are in and the value of the homes in the area.  

Depends on if you tenant still wants to live there after its repaired.Also congrats on a brand new home, insurance will likely build a new one depends on how severe the damage is.
