Of course I lost the saw with a battery in it, so two more batteries and another charger are nice to have. 

I am currently in a live-in renovation on a duplex in Battery Park that will be a rental when complete.

Additional nice touches include phone chargers and just a snack/coffee for them to grab if they are in and out.

Treat it like you would your own house if managing yourself yearly inspection :- furnace/boiler - clean out burners (do in Fall to make sure heat is on in winter)- clean dryer vents- caulk bathtubs- change out thermostat/CO2 detector batteries- clean out gutters in Fall- while on the roof looking at gutters, take a look at roof condition - fix early- vacuum and clean utility room near any furnaces and water heaters (keeps dirt/dust out of systems, can extend life)- rinse water heater screens (can fill with dust and won't stay lit)- drain water heaters yearly - prevents sediment buildup and will extend life- change furnace filters (more often than yearly)- if in cold environment, turn water supply to exterior off before winter- take a look under sinks to check for any slow leakThis shouldn't take much longer than an hour or so per unit per year unless you find something unexpected, and if you do find something then good job catching it early. 

During this year, I would owner-occupy the house and charge rent in the other 3 bedrooms, making about $300/mo.

It's never unwise to keep educating... we all need reminders even about "common sense" items... the same is true of changing batteries in smoke detectors, etc.

We were constantly getting more efficient panels and batteries such that when we went to provide warranty service on a customer three years later, the old technology wasn't even available to replace some components with.  

The shared backyard is filled with their junk which the tenants in the other unit complained about.I did a civil and criminal background search on the tenant and he has been evicted twice and has an extensive criminal records including multiple drug charges, break and enters, battery and assault with a weapon.Here is a picture of their backyard treasures:

Perhaps a conversion to "best and highest" use ;) For the record, I DID still charge rent and utilities until she stopped working!

It sounds like you have a lot of construction skills which could come in very handy - please send me more info (what you've done, what you don't do, how you charge, rates, etc...).Welcome and best of luck on your investing.Thanks,Tim
