2 cents of advise.   

any clauses or scenarios you can advise please?

This is a good reason why people kick themselves for selling early.I advise people to be very careful when they purchase a property as the costs to sell it and buy another is more than it's worth in most cases.

should I advise an engineer or Architect ? 

Thanks for the advise and suggestions.

Good advise.

Awesome thanks for the advise @Julian Gonda and @Brian GarlingtonYes I tried to talk to the listing agents but sometimes they get 20-30 offers and 50+ calls so is hard to even get a phone call answered.But I could start implementing building rapport at least via email, Are you seeing any indication of a slow down on your side of CA?

I will also always advise my customers to do a cash out refinance to avoid these issues.  

I advise against buying condos or anything with HOA fees, relying on the collective financial status to upkeep the property's common areas.

Conventional lender advised I wouldn't approve for this other project so I went the HM route.Are there banks that allow you to refi sooner than 6 months without it being a 5 year or short term loan?
