Many others on here have said the same thing, but at your age i'd focus on career.

My son (age 24) however, is an independant contractor / self employed and is trying to buy a house. 

Last year was the first and only year we had a negative cash flow, and that is driven by the anti-landlord west coast sentiment.  

Some carriers require limited water damage coverage depending on the age of the property and age of utilities.I would recommend at least 25% (ideally more) when possible and if you're limited to 10% you should make sure you cannot purchase another policy for a similar price.

Items like a missing doorbell or blinds may fall into wear-and-tear depending on their age.

Eg find contractors in ages out of state.

BTW there is a free trial and the Starter monthly plan is $119.It also allows you to search through consumer information such as property owner "credit worthiness," Credit card usage, buying power, age, language, family members in the house, and many other fields that are above and beyond property characteristics, which is unique.

In general I am anti-arbitrage but for something so unique it may make sense. 

Due to the age of the home and the appraisal we ended up closing at 10k less than the asking price.

If you can get a better deal on the home due to age its a fine and if you need financing banks do not judge year built.
