I’ve purchased an online course but I’m a visual learner and was hoping one of you could help me out.

I would avoid turnkey companies who cant give direct answers, won't allow you to visually inspect properties personally, won't allow for a 3rd party inspector to come in, and those who are slow to respond.

@Jonathan Thrasher  Half the battle in real estate investing and flipping is to be able to visualize the finished product.  

The two houses you picked as comparatives were fixed up to look like new and they had much more visual appeal on the South side of the lake.

I haven't sent that to her, I can just visualize her head exploding when she sees it. 

For example my spreadsheet list on a home that rents for $1,000 the rent from the 1st - 5th is $1,000, from the 6th - 15th its $1,100, from the 16th - court date is $1,325 ($1,000 rent + $100 late fee +$125 court cost+ $100 reinstatement/admin fee).This gives them a visual picture of what they are going to owe.

The tenant may recover the actual and reasonable cost of that other housing which is in excess of the amount of rent which is abated.Elsewhere in Clark County, NV codes:"Life-safetysystems" means, without limitation, electrical, plumbing, heating, ventilating, air conditioning, emergency lighting, audio and visual signals, fire sprinklers, smoke detectors, fire walls, and means of egress required by law for the protection of human life and safety.So, the fact of the matter is, most people do live without A/C, however your municipality, and building codes will determine whether or not you are required to provide such services, and what remediation the tenant has and what duties the landlord is liable for.

I check for signs of plumbing leakage in the kitchen and baths and do a visual inspection for any noticeable damage.  

Is there a test to see if I'm better off replacing boards or is a visual inspection enough? 

This is when a nice spreadsheet will help you visualize your cost/benefit analysis.
