I'm with a third-party Property Management all over Houston managing a little over 300 Single-family or Small Multi-unit rentals!!

I used to cold call, skip trace, send mailers, and don't get me wrong you will get success from it like James above, however as you gain experience you will realize you need deals faster, easier, cheaper, and with more "meat on the bones" and in order to have that you need constant deals flowing through your eco system and that's hard to do with mailers, cold calls, VA's and skip tracing etc.

I’m here because I’m interested in investing in small multi family units, duplexes, triplexes and fourplexes.

Most who get tripped up are those buying the smaller multi-families that don't possess the correct use permit/historical rental license activity. 

These markets feature turnkey properties, such as new builds or fully rehabbed homes that are tenant-ready, with systems that still have about 10 years of life remaining and property management teams already in place.

Congratulations on the duplex -My investor clients have acquired several multi-family investment properties locally in the market I operate in Northwest Indiana - Figure out your personal investment objective for the next 4 years and align yourself with the next property that make sense in this current market environment-

The right team should have every system in place for you to be able to go from novice investor to experienced investor after one deal.  

Applying that to RE investing, most would agree your first FHA loan should be a multi-unit house hack.

Investment Info:Small multi-family (2-4 units) buy & hold investment in Clinton.

I'd be looking at multiple structures. we try to build below the average new build cost in our market in Columbus Ohio which is 515,000 last year and we target land 40-50k and urban core adjacent where we get higher price per square foot. we build for clients with margin around $190 a sq ft depending on multi or single. we can get that down in our triplex it's a little higher on our single family homes because of garages and limited economies of scale. hope that helps. idk Philly but if you show me the area and styles of homes I can give you some more insights.
