But the answer for everyone may differ.Here are the personal attributes I see in those able to achieve a higher than market ROI, enough higher to be able to “scale”.1- Knowledge of real estate principles, real estate law and real estate finance2- Minimum 3 -5 years full time, or near full time experience directly related to real estate investing3- Ability to utilize technology for increased efficiency, capacity, and accuracy4- Excellent hired legal counsel and excellent hired marketing help5- Established method(s) of obtaining consistently high QUALITY deal flow6- Ability to manage and choose people who are NOT employees: Attorneys, Appraisers, Mortgage Brokers, Real Estate Brokers, Title Companies, Surveyors, Marketing Specialists, Accountants, Contractors, Consultants, Property Managers7- A VERIFIABLE track record of success8- Ability to identify, analyze, and negotiate a deal that can be “worked” for “enhanced” ROI9- Some type of competitive advantage; for example for me it’s my ability to analyze and identify mortgage loans that are actually less risky than all other lenders believe (on the investing in debt side), and on the real property side it’s my ability to analyze”pull the trigger” with LESS information than other investors need,  combined with the ability to pay cash, or raise significant capital almost instantly as well as being able to obtain loans at the lowest prime customer bank rate with no recourse or personal liability.  

Buy quality assets with NON section 8 tenants that have 700 fico scores thats safe bet in the US>  And what I do ..

High-quality photos and detailed property descriptions are key. 

Time, Quality, or Price- you get two out of the three.

At worst, fair chance of some quality mentors. 

So, communication and assignment issues, as well as not being able to explain the maintenance issues and the required work.3) Proper documentation and quality of work issues.

Keep it simple, paint and carpet, buy a good house in a quality area.

As others have stated, your fit & finish goals should be guided by whether you plan to:1) Rent: tenants don't always take care of a property, so you want to use lower-grade materials and workmanship.2) Flip: higher quality on workmanship and materials is usually required.Regardless, you always want to "Maintain to the Neighborhood".

If so, how do you trust you're getting a quality tenant that is safe?

@Sakib KhanRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?
