Buy from a quality builder in a neighborhood which is going to appreciate.  

Yes, you will likely pay close to or at retail value if you are buying a quality property that has been properly renovated. 

Another key aspect of creating generational wealth is investing in high-quality properties.

(Ask me how I know this.)You'll be priced out of virtually any quality market as you'll need to put anywhere from 25-40% down if you'd like to cash flow in a deal you don't have to significantly rehab (or found off-market) with interest rates where they're at (and don't expect them to go down to 4% anytime this decade either--a 3-4% interest rate is historically low and investors in the 2010s were lucky and spoiled). 

A few things to keep in mind:Section 8 requires the property to pass an inspection based on HUD’s Housing Quality Standards (basically making sure it’s safe and well-maintained).The rent you charge has to align with Fair Market Rents (FMRs) in your area, so it’s good to check what similar properties are renting for.You’ll still be responsible for maintaining the property, but the upside is that a chunk of the rent is guaranteed by the government, which can provide steady income.Check with the local housing authority about any specifics for your area—every jurisdiction does things a little differently.This could be a great niche if you can find a good deal on the land and make sure your expenses (like maintenance, insurance, and occasional vacancies) are covered by the rental income.

You should focus on the quality of the agent, not the amount they charge.

@Renee LeFevreTo rent out your basement, follow these steps: check local regulations, prepare the basement with separate entrance, screen potential tenants, draft a lease agreement, set the right rent price, consider tax implications, update homeowner's insurance, and build a positive tenant relationship to attract quality renters.Good Luck!

We pay a few hundred dollars for a professional quality pitchbook with the financials and that has been money well spent.

Second most important thing is can they tell me the quality of tenant I will be renting to.

High price for low quality service.
