Follow this advice to get the best from your self build project:
1)
Pull together a good financial plan that shows all your project costs, contingencies, fees, loan payments.
Package this into your projected sales value and calculate your headline profit. Since your scheme is all about profit, have this plan in front of you at all times (except when driving of course!)
2)
Learn about taxation. You can build a house, sell it for profit, incur no tax and get all of your VAT back!
3)
Land is your biggest cost. Be creative about finding hidden opportunities. There are parcels of undeveloped land and low standard houses that can be demolished in every county.
