One person who was looking into investment properties once asked how much they needed to prepare for a down payment. They were thinking similarly to when buying a primary residence, but comparing buying a rental property in Plano to purchasing in neighboring Frisco or Allen shows that the funding structure afterward varies more significantly than the down payment itself.

First, looking at the down payment criteria, it is generally higher for investment properties, ranging from 15 to 25 percent compared to primary residences. A credit score of 620 allows for loan approval, but to receive relatively favorable interest rates, a score above 740 is necessary, and rates are set 0.5 to 0.75 percentage points higher than those for primary residences. Additionally, lenders only consider up to 75 percent of the expected rental income as qualifying income for loan eligibility.

If we examine how Plano and nearby areas differ with the same budget, according to RentCafe, the average rent in Plano for 2026 is $1,689, which is a 2.26 percent decrease from a year ago. This slight decrease in rent signals that a more conservative approach should be taken when calculating the rent-to-purchase price ratio.

Like the rest of Texas, Plano, which is part of Texas, has no rent control. Under Texas Government Code Chapter 2143, it is prohibited for cities and counties to set rent caps, so regardless of how much you prepare for a down payment, there are not significant legal restrictions on rent increases.

Property taxes are another aspect that should be considered alongside down payment plans. The average effective property tax rate in Texas is around 1.6 percent, and in Plano, which is in Collin County, the actual burden often increases when school district taxes are added. The Homestead Exemption does not apply to investment properties, so taxes must be calculated based on the entire appraised value, which is also a factor to consider when determining the size of the down payment.

Comparing cases where a generous down payment is prepared versus a minimum level, the monthly repayment amount and cash flow flexibility can vary significantly. Checking whether the monthly rent exceeds 1 percent of the purchase price, known as the 1 percent rule, along with the cap rate calculated by dividing net operating income by the purchase price, can help determine how much more to invest in the down payment. If management is outsourced, 8 to 12 percent of the monthly rent goes to fees, and it is realistic to expect about 1 percent of the asset value annually for maintenance costs.

Landlord insurance, which has broader coverage than standard homeowners insurance, should also be included in the fixed costs incurred monthly after the down payment. If there are plans to switch to another property later, the option to defer capital gains tax through a 1031 exchange is also worth considering in the long term.

Plano has many school districts preferred by Korean families, resulting in relatively steady rental demand; however, even within Plano, the western and eastern areas show different school district ratings and rent levels. School district boundaries change frequently, so it is advisable to check the assigned school for the specific address before purchasing.

Plano is home to several corporate headquarters, leading to consistent rental demand from families relocating due to job transfers. This demand can fluctuate with the economy, so it is also worth checking whether rental demand is overly concentrated in a specific industry when determining the size of the down payment. It is important to remember that Texas has no state income tax, which should not be overlooked in net income calculations. When deciding on a down payment, it is also good to calculate the cap rate by dividing net operating income by the purchase price. This figure reflects all management fees, property taxes, and insurance costs, providing a more accurate picture of actual financial planning than a simple rent ratio.
