在好区维持一个房子在市场上READY FOR SALE的状况是费用很高的，特别是拿出去出租。

我随便给你算笔帐。

This is a SFH in a good neighborhood, not a slum house, has much higher repair cost because you have to do a higher standard, can't just fool around (that will decrease your property value).

Roof: each 15 year, $7500, each year $500.

Interior Paint: each 10 year, $3000, each year $300.

HVAC: each 15 year, $4500, each year $300.

Appliance: each 15 year, $1500, $100.

Total so far: $1200. Now take a breath...

Remodel 

1 kitchen each 20 years: $20k 

1 master bath each 20 years: $8000

1 and half bath each 20 years: $5000.

I have said nothing about floor and carpet, cut trees, refinish driveway, etc. etc. etc.

如果您拥有过房子１５年以上就知道这是最起码的数目。

所有这些维修／更新都是按职业公司来做的质量不大打折扣。
