katie I will piggy back on your plan and Belinda suggestion which are great by the way. I will add that, if possible:
1-Cash out refinance your current house to the max amount you can take out, if I'm not mistaken in some refinance you will skip a payment or two depending on the day you close (you probably know that already as a realtor)
2- Advertise you current house as a lease purchase and ask for 5%-10% no-refundable down payment make the rent amount higher than your mortgage payment to create some cash flow. The tenant end buyer is responsible for all the repairs and maintenance. Make the final purchase price slightly higher no matter the comps, a house is only worth what someone is willing to pay for it. Have in mind that most of the buyers that will apply have some sort of obstacle that they cannot go to a bank and get a loan, but that doesn't mean they don't posses the capability of pay a premium for the privilege of owning in the near future, if they don't come through with the agreement to purchase your house at the end of the term then you get to do it all over again with a different buyer, collecting another down payment and keep paying down the mortgage with their rent. Also their rent don't count towards the purchase price only the down payment and extra money above the rent amount, and that is only applicable if they buy the house at the end of the lease term, if they decide not to go through with it, they are saying bye to all the money they paid.
While you are leasing your house with terms and collecting down payments, the rent is paying down your mortgage, you are getting cash flow and you don't have to do any maintenance to the property.
3- Find a cheap place to rent, let your landlord do the maintenance. A thing to consider about the school district: I used to live in Rincon and my kids use to belong to Blandford Elementary one of the best schools in Effingham in my opinion; but then we moved to Guyton and they changed them to Sand Hill, well my wife didn't like sand hill and she requested to leave them in Blandford, the only down side is they have to be car riders, they can't ride on the bus because is out of district.
Back to Funds...
So while you are paying cheap rent, leasing your house, and collecting all this money then is time to find some lease purchases deal yourself or owner financing with low money down. Find a house that still have a mortgage on it and offer to take over the payments or lease purchase it from the owners with the right to sub lease it and use you end buyer down payment to pay for your down payment with the seller. This strategy works best is there is good cash flow and the house is fairly below market value since you will be making payments to the seller sometimes up to market rent. Let the equity build up and refinance to take out the seller. That will lower you monthly payment and increase you cash flow.
Find a owner that will let you do owner finance with a low down payment, there is so many creative ways to structure a deal with owner financing. Right now I have a house that I am ready to buy with owner finance with nothing down, principal only payments with a one year balloon. A year might not sound good but no interest sounded better and I get $200 cash flow from my end buyer, his rent will pay for my payments to the seller and I will only owe $45k at the end of the year, after getting a loan, my mortgage will be around $390 and my cash flow will increase to $500 per month.
Last piece of advise is: use you marketing money wisely, if you don't have a lot, scrubs those lead list good for potential deal and correct info. I did a campaign of 390 yellow letter, all homemade, with a list a acquired and at least 100 have come back undeliverable, some came back with land parcels without a house, some came back with address incomplete, no mail receptacle, the person doesn't live there no more, right out of the gate I lost almost half of the money I spent. So now I look at every address ( do to my lack of funds) to make sure my mail pieces make where I want them to go.
I hope this helps. let me know if I can be of any help.
