^^ Not sure if you have ordered the setup, but this is how I would go.
TP-Link TL-R470T+ (2WAN: 90+25Mbps) -> Ubiquity wifi AC LR AP 1 (POE from TL R470T)
Ubiquity wifi AC LR AP 2 (wirelessly extending the network same SSID via wifi uplink) (POE via adapter )
This would easily cover your 1000 sqf house.
I have ordered already. I thought about Ubiquity, but I have limited option with wiring. All network devices are hidden inside living room media cabinet. So, Google Wifi is a better alternative I suppose.
