The First steps of buying process are: 

 Find a property you can afford

 send us an email presenting an offer , an agent will respond 

 Find our  Real Estate Agent 

 you chose your dream house 

 Coordinate the Paperwork

 congratulation you bought  your dream house,  the sale is closed 

The number of houses to view can depend greatly,  However, it's likely viewing  at least two or three homes, preferably with the same agent, on the same day this allows you to compare and rank properties  and value.

Don't view more than 3 a day,  you will get exhausted and will not make rational decisions after too many viewings.

A final walk-through is not required
