Each strategy produces slightly different rent rates.

I personally believe single family produces the best rents and appreciation.

What’s the best way to attract investors who understand the vision of a multi-decade endeavor like this?

These markets tend to attract a lot of investor activity, which can drive prices up, leading local homeowners to take on more debt to afford homes in their area."

Well, those properties will statistically attract corresponding Class B & C tenants.So, how should an investor account for Tenant Payment Performance/ DEFAULT in their analysis? 

And for most of my clients, they are generally attracted to a city or market for personal reasons and THEN then find a property that works for them rather than looking at general market numbers...meaning, my clients can make money in ANY market, even ones where the population isn't growing, the rental demand is softening, and the rent-to-price ratios are less than attractive.So to you, does PA mean Pittsburgh, Philly, or central PA?

It is normally the real estate that attracts the nuisance tenants which leads some to resort to section 8 believing its a cure all which is the furthest from reality.  

He believes that area where he will be buying the new homes is going to appreciate and attract more MTRenters, but now, the big difference is that he would now have 3 properties that can go up (or potentially down) in value, go up (or down) in rent, and three times as many vacancies to fill.My back of the napkin assessment is that for only a drop in $200 a month in cash flow, he would control a lot more assets with growth potential and as rents rise over the coming years, the combined rents will increase to a total more than the single rent.HOWEVER.

Therefore, your long-term income depends on the city's ability to attract new companies.

While metrics like square footage or price per square foot matter, the number of bedrooms, bathrooms, and overall location are often more critical for attracting tenants.Engaging a property manager early on can save you from costly mistakes and help you invest in properties that perform well in the rental market.
