Hi Peter, hang on to that enthusiasm - on a bad day it may be what matters most! I'll give you my perspective, take what you like from it..as it is going to be extremely condensed but you'll see the tips of the icebergs at least. In my version of all this, I like to land on a rehab once I already have a buyer picked out an prequalified and I know where they want to buy and I can walk a deal I have under contract and do a scope of work and upsell the cabinets,floors etc (manage costs) and the potential buyer is excited about moving into a customized new home instead of a used home. This scenario shields you from over/under fixing and you walk into the deal with eyes wide open. This means I would start my marketing now for buyers. I have a wholesale price now, say $10k net over acquisition cost. (That amount is relative, to market - in CA or south Florida, might be $50-100k.) So if I had a cash buyer that wanted the deal, I might consider making the $10k and move on, which can mean avoiding some issues that come with rehabs that even bother experienced folks - let alone blindfolded, first time at bat, right? At the same time, you need to be getting good multiple quotes from contractors with licenses (that you verify) - and they need to include detailed scope of work, PERMITS, blueprints, and timelines. At the same time, if you are not already very familiar with what your ARV is, look at past sales in last 5 months (because rehab might take 30 days minimum), with in .5 miles, +/- 15% square footage, +/- 10 years, about same land size (or adjust). Throw out bottom bad, top extreme, average the rest and that is probably the most $/SF you get for the property from an FHA end buyer...so that is the most it might get through underwriting..the end of the world, standing tall looking good. Your starting price would be above that obviously, but NEVER at or below to start. If you did everything right and retailed it, that number minus your repairs and acquisition will be your profit (or loss). If you lose, don't stop, just get better. If you make something, be thankful and figure out what went right and what could have gone better!
Also, as for getting the offer accepted, here is a perspective..again..just get what you want out of it. On an average week in an average month in an average year, most real deals that come out on MLS (I am assuming this is where you got it - but if not, the advice is still free) are scooped up by the big dawgs and cats within first 48 hours of going on market. Anything left after that will be marginal or worse. If the deal is still around after a week or so, it might be worse and gets worse. Start to ask yourself, why is this deal still available, what do all the people who already do this for a living know that I don't know and so they avoided this deal? If you think you got good answers and proceed, be sure your first offer is so low it gets rejected; if it does not get rejected, you paid too much. If it gets rejected, now you get to work on negotiating. Now is where it's best to already have your buyer list in place and know intimately your costs & ARV before you accept a number just to do it and jump in - otherwise its no longer investing, it's blindfolded baseball. (Some people can afford to play blindfolded baseball and love the thrill because they can afford it - so to each is own - if you don't own a bat and a blindfold already - get the numbers down and buyers in place before next time.)
Hope you got something out of this even though its not exactly what you are asking for. What you are asking for above is quite a lot actually, so do your best alone or try to partner with someone and do it with them. Good luck! Oh, and if you decide to wholesale it, pick your price and send me details, can't promise I'd be interested in it, but I'd look at it.
