Sometimes she changes light bulbs and replaces batteries in remotes and thermostats. 

Did it need updated smoke detectors and are you using 10 year life battery detectors or 9v battery operated?  

It might not have addressed your past issues, but I now put $10 battery water alarms next to the washing machine, water heater and under the sink.

Its purely networking and a great opportunity to meet fellow investors who are doing great and also folks starting out.

If market lease rates for our make-believe building are $20/sf NNN and the target cap rate is 7% then the land can arguably be sold for $1,356,000.00$20 x 15,246 SF = $304,920 gross annual income$304,920.00 x 7% cap = $4,356,000.00 value$4,356,000.00 - $3,000,000.00 construction costs = $1,356,000.00Please note this is a GROSSLY over simplified analysis and there are far more costs associated with a new development than the pure building construction costs and land costs but you get the idea. 

My PM's contractor gave us an estimate of things to be repaired and it includes things like $50 for replacing smoke detector batteries, $50 for repairing shower handle, $60 for caulking tub, $200 for changing locks.

@Kevin Colwick, here is the interior- repair/replace damaged sheetrock- wipe down and clean all walls throughout house- wipe down and clean all doors and throughout house- paint trim and doors- replace missing/broken blinds- replace missing/damaged doorstops- replace all light switch and outlet covers- replace missing/broken light bulbs- make sure all doors open/shut properly- make sure all windows open/close properly- replace air filter- replace batteries in the smoke detectors- remove all trash from attic- remove all trash- wipe down and paint all ac vents

For instance, purely on a cash-on-cash basis, if a 3-4 unit property will cash flow in the $500 range, then you can "recover" your $7K (+ closing costs) in as little as 14 months.

Many smart thermostats say you can install it without power from the furnace, but this just means it's running off batteries.

Howdy @George ClouseFrom a purely numbers prospective the analysis looks good.
