I wouldn't want someone to hold back, I prefer honesty and straight talk. 

However, what if you prefer simplicity, limited risk, and are living off of the income? 

I prefer graduate students whenever possible because they don't have time for partying, are of legal age anyway, and generally tend to be by themselves or with a partner so it's more like renting to a couple.

The ones that truly understand it often don't want to be bothered, so, slightly back to one, are assuming that any outreach is bad news, otherwise, let it go.Everyone's preferences are different, but I found sending out a semi-generic email with a link to schedule time with me was the best way to reach the most people, and people that wanted to talk without making them assume something bad was happening.  

Experienced managers can help evaluate potential investments by providing insights on rental demand, market rents, tenant preferences, and location-specific factors that affect leasing success.For example, rental properties need to be close to conveniences like major roads, shopping, and schools.

Some people need 2% above the borrowing cost (8% cost of hELOC you gotta then make 10% + etc) and others will want to double their cost of capital or 200% so it depends.Everyone's going to give you their anecdotal experience or what their preferences are so its good to hear it all and determine your own.

I prefer public comments here before you send a direct message, though. 

However, without more information on what your preferences are, it is difficult to give you good advice.

I'd prefer a small business.

But, I prefer 3rd party over self management right now because I have higher priorities and just have to purchase properties with thicker margins to absorb the added vacancy and repair costs.
