I would appreciate your advice about  the correct numbers to use when estimating closing costs while running the numbers for our next purchase.This is an example of the closing costs for a rental that we purchased for $105,000.Loan Charges:  Origination & prepaid  interest:  $1,000Title Charges & Escrow/Settelment:  $1,600Impound Charges:  Tax & Insurance:  $1,500Total:  $4,100Which of the charges should be entered into the closing cost field?  

For example, even if the carpets or flooring were brand new when they moved in, and they're now completely trashed, you've had more than a full lifetime out of them. 

Do they say that about Bankers, Grocery Store Owners, Doctors (well maybe doctors..bad example) plumbers, etc?

As an example I would assume Park Cities, Southlake etc. to be A +

If I sell it to for example....

For example (try  not to repeat the items listed below):- Laundry room or add washer/dryer in each unit- New roof- Individually meter each unit electric/water- Add small park- Update curb appeal to include paint.- Add small workout gym to leasing office- Update pool area with pavers and outdoor furniture-- List yours below --

For example, the condo that I'm looking at was sold in 2012 for 50K, now selling for 150K.

An example: I've found a good deal (I've run it through the BP calculator and the numbers are excellent).

Wa, cali, Nevada and NC for example all same thing.

Everybody who provided detailed "Rules"  and examples I do value and respect your input and take away that it would clearly be a good idea to plan more for unexpected expenses.
