I closed in about a month with FHA starting from the time I made my first offer. It could be as quick as three weeks if you can hustle on your inspection period and have a good lender. You MUST be pre-approved to make things go more quickly, eliminate risk that you won't be able to perform, and frankly, to get RE agents to event give you the time of day. Sellers will be hesitant to accept any offers from someone who isn't pre-approved in fear that they will tie up their property for a month with a flaky buyer and miss out on other opportunities.
A little bit about my particular deal...perhaps you can draw ideas or similarities.
When I got my FHA loan, I locked in a 3.75% interest rate about 1.5 months before I actually closed. FHA requires a ton of pre-paid PMI in addition to the monthly PMI. My closing costs would have been around $25,000. I lowered my closing costs to around $4,000 (including appraisal) by accepting an interest rate of 4.25%. Since up front cash was my biggest hurdle, and I wanted enough cash reserves for any issues that could arise, I the 4.25% option (the payback period for this decision was about 10 years. I don't plan on having this 4 plex for that long, which is why I chose this). Mortgage insurance for FHA is 1.35% right now. For me, this amounts to $456 a month.
I purchased the property at 3.5% down with $4,000 closing costs, so I was all in at around $19,000 up front cash. You can always make the seller pay closing costs and just bump the purchase price accordingly. My wife and I live in one unit and "pay ourselves" rent of $900 a month (for a place that should cost $1200) to make the place break even. $600 of every payment we make goes towards principle. Just by these numbers, this isn't the world's greatest deal, which leads me to another point. If you want to buy an undervalued 4 plex, you will most likely be inheriting tenants who are paying rent way below market value. In may case after moving into one of the units, I inherited one year leases that all end at different times of the year. This should be factored in to whether or not you can "afford" the property, as you may carrying the property for a year or so, when it actually may still be a great deal.
My leases are all up in 5 months or less, and I conservatively project a 30% increase in rents, which means I would be able to live in my unit for free, and enjoy a "theoretical" 30% increase in my property value. IF I can get my property appraised for 21.5% more than what I bought it for, I've suddenly showed I have 25% equity, meaning I can refi and get my $456 a month PMI away and free up my ability to use the 3.5% down FHA loan again. I'll then move out, my total positive cash flow being around $1,400 a month with an additional $600 a month going towards principle and own a property valued at approx. $125k more than I paid for it. This all happening in less than a year. My plan is to do it all over again. This isn't necessarily my life long strategy, but is a way for a 22 yr old to get in the game early.
Moving back to reality, these are all projections, which I feel are realistic and conservative. I have NO track record of real estate success, and experienced investors may see serious flaws in what I just said. I just thought I'd go into depth, because it appears you and I had very similar situations and mindsets. To be honest, I really had no mentor and wasn't a member of BP yet, so I'd be really curious to hear what more seasoned investors have to say! It's in the Portland area by the way.
