Estimate Rehab costs

This was actually cheaper than what we estimated it would cost to repair the existing unit.

I'm about 7 days away from closing on my first real estate deal and the thought occurred to me that instead of wasting time (and closing costs) dealing with a bank for the initial loan, I could simply use myself as the source of "private money" for the entire purchase (~40k) for a home that I intend to rehab.The rehab is expected to take 3-4 weeks and I already have a reputable contractor with a written estimate in hand and the cost will be a ~25k additional (worst case) on top of that.  

@Joel Pash Joel, I need to know more details to help you with "Estimated repair cost".

Any tips on how to analyze the potential rehab costs of a 4plex to estimate what my 203k loan would look like?

Currently in the process of estimating how much I can borrow and finding brokers/agents.

I have an appointment this weekend to see a triplex that seems like my best chance for a deal so far. 

I’m asking for nothing more then a chance to learn and prove myself.

My bank doesn't require me to wait so I can put a mortgage on for 80% appraised value right away (estimated $64k) which puts me in the house with between $10k - $15k in the bank and a good cashflow on the duplex (about 15% return after expenses).This is where it gets tricky...If I rehab this to top market I could probably sell it for $120k.  

no absolutely not but at the same time I'm going to be cash flow positive based on conservative estimates and only have about ~10k into the deal.Here in NJ, the higher HOA fees are offset by the lower taxes on the condo.
