I understand some realtors might not want to spend time digging up things for investors, but the OP asked what investors look for, so I provided my view of the world.The auto-collectors for filtering property close to useless - it doesn't help me to get streams of listings from some realtors that I can easily find myself through all the aggregating sites. 

Even if you find that you still need money to close, due diligence costs, and some reserves to eek by until you can build up the cash stream.

.- Boosts Your Credibility: Being known as the person who knows what's best, even when it's not your deal, sets you up as a true expert in the field.BTW, you can also make money with referrals: Redirecting a seller to a service that better fits their needs can still be profitable for you, establishing another revenue stream while maintaining your integrity.The line between wholesalers that stand out and ones that burn out is how well you respond to seller needs.

After that, my goal would be a steady stream of income while I take a few months to re-assess and figure out the next step in my career. 

What are your primary revenue streams?

The city's strong rental market driven by a growing population ensures a steady income stream.

get an umbrella policy to protect yourself, see if you need a rental license in your municipality. an LLC is only for insulating you for liability and anonymity, it will not save you on taxes and you really dont need to worry about it with one property imo . you cant protect a single property from lawsuit, insurance is what covers you just make sure you’re up to code. insurance will always look for a way to get out of covering an incident.if you register, you’ll want to report the income. if you make less than expected after deducting costs, then it’s time to raise rent. you wont be able to reduce more to reduce other income streams since you're not a full time real estate investorin the future if you ever sell, because it’s a rental now you will owe capital gains on the property. philly is probably like ohio and not california with it’s YoY growth being tied to inflation. with that said your profit is mainly going to be the equity you build from your tenant paying your mortgage. the money earned monthly should be saved as youre doing in case you have a capex repair/replacement come in like HVAC, roofing, etci advise you pay for an hour to speak to a CPA to better your options.good luck

There are so many revenue streams and upsells available and it's the high end properties that are succeeding right now. 

I would think about this in terms of whether or not you can get additional streams of income faster than your money can accrue interest?

As far as a multi, personally if all things were equal I'd go for the multi for a few reasons.  1) Added diversification.. if one tenant doesn't pay, you can still cover property expenses with the other tenants 2) Shared capex... typically, one roof and one property to maintain but multiple streams of income 3) Less vacancy.. usually multi's rent for lower, for example one of mine is the sweet spot of 3 bedrooms for $1300.
