@Wade G.
I can apporeciate your dilemma. You are in aquisition mode. You need cash to make downpayments on the next rental properties you plan to purchase. My question for you is, do you have a strategic plan, or, are you just in buy mode with no coherent plan in place?
If you don't really have a well-defined plan, let me ask you what your financial goal is. Are you tyring to generate enough rental cash flow to replace the income from the W-2 job you want to quit? Are you buying properties to provide a sustainable income for your retirement? Since you are investing in rental properties, I assume you know that buy and hold investing is a slow road to wealth, and, by default, your investment strategy is a long term undertaking. If you have a long term goal in mind, when do you declare success?
If these questions are giving you pause. then let me give you a plan to think about. Let's say your ultimate goal is to be financially independent (not the same as rich or wealthy, but better). You want to have your passive income support your lifestyle so you never need to ever work, or put a deal together to put food on the table. Sound good?
How much passive income will you need? If you think you will need $4000 per month to maintain your retirement lifestyle, then how many rental properties will you need in your investment portfolio to provide that income? If a financed property generates $100 monthly cash flow per door, then you will need 40 properties. If a free and clear property generates $500 per door, then you only need 8 free and clear properties.
Once you have identified the number of properties you will need. we can put together a strategic plan to get to your goal of financial independence so you can retire. Let's say you have 30 years before you want to retire. Start by using the 50% rule (rule-of-humb, not absolute). Half of your rental income will be needed to pay the costs of ownership and rental operation (repairs, vacancy, upkeep, major systems replacement, property taxes, insurance, property mgmt, advertising, etc.). Half of your rental income will be needed to pay the debt service on your financing and leave enough to meet your cash flow requirement. If market rents in your rental market are about $1000 per month, then your debt service can not exceed $400 per month. If your fixed rate financing is 4%, then the most you can afford to pay for a property is $105K with a $21K downpayment. Your monthly principal and interest payment will be about $401.
Let's say you are able to save the downpayment to buy one property per year for the next ten years. Let's also contribute all your excess cash flow from the property (properties) you own toward the downpayment savings for your next property. At the end of ten years, you have ten financed properties, all producing at least $1000 per month gross rent. If during the ten year acquisition period, financing rates increase, then lower your maximum purchase price for the next property.
With 10 properties in your rental portfolio, you can stop the acquisition phase and begin your debt reduction phase. For the first property you purchased (the property with the lowest loan balance) use all of your excess cash flow to pay down the principal balance on that loan. When that property is paid off, establish an "escrow" fund for the property taxes and insurance premiums that your mortgage company used to pay for you. Contribute to this fund monthly. When the first acquired property is free and clear, you have more excess cash flow to contribute to debt reduction on the next lowest loan balance. Regular rent increazes will let you keep pace with increases in property taxes, hazard insurance premiums, and general operating costs. At the end of twenty years of debt reduction, you may find that 5 of your 10 properties are now free and clear with 5 more still with a loan balance. At this point, you should be able to sell two of your financed properties (pick the least productive properties). Use the proceeds from the sale of those properties to pay off the loan balance on the remaining three properties.
At this point, it has been 30 years since you began your trip down this slow road to wealth. You have eight free and clear rental properties generating all the cash flow you expected to need to support your retirement lifestyle. You don't have to work or put together a flip to put food on the table. Your primary residence should also be free and clear. You should not have a car loan, nor much (if any) credit card debt that you don't pay off every month.
If you need more money than you have in savings, take out a home equity loan on one of your rental properties for $25K tax free. Arrange your payment schedule to pay this loan off in seven years or less using the rental income from the property you refinanced. You can even do this every year for the next seven years. When you are refinancing the eighth property, you are paying off the refi on the first property so you can refi it again the next year and start the cycle over again. If your rents are high enough, it should be fairly easy to keep this $25K per year tax free income stream going for the rest of your life.
Notice, I did not offer an opinion on whether it is best to take on more debt or to pay off what you own first. I think there is a time and place for both depending upon your goals and the circumstances.
Just food for thought.
