Lots of people have owner built in the past .. when borrowing was easier.
When I am valuing their house for refinance years later I always ask them this "would you do owner builder again"
80% say “no” or “no way”.
It can be far cheaper to go with a volume builder such as the Henly's, metricons, porter daivis' of this world, than do it yourself.
Progress payments are a nightmare, I hate doing them on owner builders .. they are always desperate for funds .. but I have to recommend that the bank retain enough funds to finish the place at full commercial rates .. sometimes they get very little in the form of progress payment.
It goes like this .. you think you can build a house for $250k. I believe that the actual cost of having a builder (not a volume builder) build the place is $350k.
The end added value of the improvements is say $325k (cost does not equal value)- great you are saving $75k. Say you find a bank that will lend you 75% of the end value, that is a loan of $243k - almost the whole cost you expect .. great eh?
So you got the slab down, usually this is a 15% (deposit 5% and slab 10%) progress payment.
You have spent $25k of your $35k in cash on this .. plus you have foolishly prepaid some tradies (it happens heaps) and have bought the tile you want for the floors at say $8k, stored in your mothers garage ... so you have used almost all your funds getting there.
I tell the bank that they need to retain 85% of $375k to finish the job. .. the bank needs to retain $298k ... your construction loan is $243k .... they will not release a cent to you! ..
SO you have the slab down, prepaid part of the pre-fab frame and have some nice tiles in the garage .. and you are stuck.
You hit you parents up for a $50k loan on their house to see you through.
You spend this getting the frame up - the next 15% of the cost, $35.5k.. I do a progress certificate. The bank needs to retain 70% of $375k ..$262.5k .. you still do not get any funds from the bank.
You hit your grandma up for the next $50k .. it costs $3k in expenses to do this which you promise to repay at the end. You now have $64.5k in the bank
You get the place locked up .. this is the big one in terms of costs and the progress payment is 35%, so this costs you $87.5k (35% of $250k). You owe the tradies and suppliers nearly $20k at this stage and they are pressuring you. .. plus the $103k you owe to the parents and granny plus the interest bill they are covering for you.
I do a progress and recommend that the bank retain 35% of $375k or $131k .. so they release you $102K .. at this point you will finally be ok.
Just remember traides will put you at the bottom of the priority list in terms of turning up .. if one is late then the whole process can be thrown out of whack .. plus you will notgernerally get the same prices they charge the builder form whom they get most of their work.
And I will almost guarantee that it costs you $25k more than you thought it would .. total $275k ...
Plus you owe your parents and grandma $15K in interest .. and your build time has run to 18 months so you have also paid an extra $15k in interest on the land and the progress payments .. oh yeah not to mention the extra 9 months to one years rent you had to pay during the delay ..
You relationship is in tatters .. and Henly would have built the whole thing for you for $325k all up.
If you go down this route have a whole heap of funds available. Also no matter what you have bought .. appliamces, tiles, windows etc.. until they are affixed to the land in some way you will get no money from the bank for them.
I trust this helps.

PS.. I was looking to owner build in the not too distant future .. I intended to fund the whole build cost from savings and cash flow .. it is just not worth dealing with banks IMHO as an owner builder. But factoring in lost income, I won't save myself all that much .. so I may just get a builder.
