If you dumped that 10k into this place then your capex/maintenance shouldn't be 20% since almost everything would be new/reconditioned.60k purchase15k down payment (25%)5.4% interest555 per month253 P&I, 215 HOA, 36 tax, 51 insurance,900 rentLeaves you with 345 mo, and 10k in the bank for reserves which is = to about 39 mos of set asides (20% maint/cap, 8% vacancy).If you get your loan to 5% vs 5.4 you're at 490 per mo and that gets you 410 left over.

They feel like I'm getting money from the government because of them and I have to replace everything they feel to - burned light bulb, filters, batteries etc.

I have been changing the batteries every 2 or 3 months (4x AA).

In the meantime some ideas might be, battery powered camera/alarm system, install a generator, ect.

Think of how many gas stations there are and we will need that many places to charge the batteries.

If you were to keep it, and were able to rent it for $1400/mo, by your calculations, it would barely produce a profit of $1200/year, and the tenants would surely be hard on it, and it would need to be reconditioned before sale.  

My home town just secured a massive deal with Panasonic to build, drum roll, EV batteries.

No need to worry about keys or re-keying anything, and I change the one 9 volt battery once a year and it works perfectly.

I would tell them to buy their own security cameras and battery powered door alarms, and they can take it with them when they move out.you provide a home that has functional door and window locks.

Good managers deserve to take a break from the park and recharge their batteries.
