I increased my income every year by starting businesses and increasing my passive streams of income. 

Figure out ways to generate a stable second stream of income perhaps.

With seller financing you have a lot of room to match the debt service to the income stream.

Also look at tax value, and use software like prop stream to see what’s sold off market.

I have a normal W-2 income, but I own/manage rental properties as another stream of income.

Be careful, as "comparable" is a relative term and rental revenue streams on vacation rentals tend to vary more widely than on SFR.

Investing in a property with the goal of renovating and renting it out can provide a steady stream of rental income.

Any spare time can and should be used to create an additional stream of income, side job, side business etc.

Sometimes it's better to work alone, keep the money, and invest it as quickly as possible to set up a second income stream that can eventually replace your landscaping business completely.On to greener pastures!
