Hi @Eder D.,
It is awesome to see your interest in the Orlando market as I graduated from the University of Central Florida and am extremely familiar with the area. I have closed on properties in East Orlando (UCF Market), Winter Park, Winter Garden, Lake Nona, Windermere, Clermont and most places in Seminole and Orange county. With that being said, I did review your numbers and have some questions for you?
#1 - What is your "Why?" behind Orlando? I have spoken with hundreds of investors that are initially attracted to Orlando / Central Florida market from reading something online only to have a very un realistic idea of what they can find. Is there a specific reason that is tying you to this area? The Orlando market is super diverse and is very micro specific and requires a lot of due diligence. The markets you mentioned above for small multi family are some of the most competitive, saturated markets in the state...its not all bad as there are certainly opportunities (like anywhere else) however I think you will need to change your strategy or find another location for the plan you highlighted above to work.
#2 - Since you mentioned your goal was to buy a Duplex, I am assuming you are planning to purchase the property as a "primary home" with the option to do a 3.5% downpayment FHA or 5% downpayment Conventional loan and then live in one unit while renting out the other unit..can you confirm this is what you are looking to do? If this is the case, you will need to account for "Private Mortgage Insurance" which is added on to your monthly mortgage since your downpayment is less than 20%. This can be anywhere from a $100-$400 extra monthly cost and depends on your individual credit profile along with the loan amount. Your interest rate at 4-5% is to low and the current environment for rates is closer to 7-8% for primary purchase which will make a huge difference on your payment. I know there are options to buy down your rate but they are costly $$$ and you will have to see what makes the most sense. Your Insurance cost (very general) at $2,700 seems low for what you are looking for but its still within range. You will need to bump your taxes up by close to 50% of your estimated $3,700 with the markets that you mentioned above. I am afraid the goal to cash flow, live for free, or even just break even is going to be hard with running general PITI numbers....thats even if you found something that could work which leads me to my next point.
#3 - A Duplex under 400k in any of the areas mentioned above do not exist and you will still be hard pressed to find a good one in another area of Orlando. The ones that do exist under 400k in the Greater Central Florida area will be 1+ hour out from Orlando/ in an area that is in a war zone/ built in the 1930-1960's/ requires a ton of work/ manufactured, or in an area that is not investible IMO. To give you reference, the starter end single family homes in UCF/ Winter Garden tend to start at 400k...much higher in Lake Nona or Winter Park. Lake Nona townhomes tend to start around the 400k price point.
#4 - If you wanted to purchase a pure investment property to rent out (not living in) will require a minimum 15% down payment with Conventional Financing however most lenders are going to set their requirements at 20-25%. Even at 25% down it will be very expensive for an "Investment Loan" with upfront points/loan costs at 1-3% to give you a general idea and interest rates being 8-10%.
#5 - Areas such as Ocala Florida have great opportunity for New Construction and am currently building a handful of Duplex(s) for around 250K all in that sell for 425-500K depending on specific location, finishes, size ect however we are getting great deals because we are using cash to build these. We are keeping as long term rentals. My team and I have had to shift from purchasing properties financing as we were doing just a year ago when the rate/financing landscape was much more favorable to now using cash to make deals work. This may be an option for you.
I hope this gives you a better idea on the lay of the land and feel free to PM me with any further questions specific to Orlando or other area of Florida.
Best of luck!
