Of course, of you buy a 5-10 year old house, you're likely to need to do some repairs/replacement during the 5-8 year holding period you're looking at anyway. - One advantage to buying a newer home is that you're more likely to get some on the in features already- granite countertops, open floor plans, etc.
If you are uncertain about how much to give, just to tip based on your bill. Generally, 10% - 15% of the bill is the most proper amount. For the tour guide and the driver, 10-70 RMB (1 - 10 US dollars) a day per person is adequate.
On how much to tip your Uber driver Well the standard tip for a taxi is 15 to 20 percent. And that is my initial reaction: I would say tip 15 to 20 percent of the fare. But things get really dicey with Uber because they have dynamic pricing. What might be a $40 ride to the airport at three in the afternoon could be a $150 ride at peak time. Do you tip 20 percent on $150?
