Steve, the question should be more along the lines of whether you want to build a retirement fund vs try to bring in passive income now.

Hi,I have a 4 unit rental building in St.Louis, Mo.

I chose to build my PM business from ground.To create a working system and to organize processes is difficult in the beginning, but to my experience it is possible to create a working model based on personal knowledges and then to provide a high level of service to the clients.

Can anyone recommend a design build company that would handle any zoning needs with the city, as well as complete the construction and leave it rent-ready for me? 

@Viral Mehta While self-management is definitely feasible, it does come with its own set of challenges, especially when managing from an international location with significant time differences like India.You’ve outlined the major tasks well, but there are a few additional considerations:Vendor Relationships: As a property manager in the Dallas-Fort Worth area, I can confirm that having established relationships with local vendors can significantly impact both the cost and quality of maintenance services.

If looking for stability, I would look at buildings built in the 1980s or newer, ideally townhome style instead of apartment style if a 4-plex, minimum 2 bedroom units.LEARNING RESOURCESI am going to try to keep up my blog here on Bigger Pockets specifically with 2-4 family units in mind.

I think relationships with the owners are very important as well - the more you can developed a relationship with current owners the more likely they are to "help" a newer investor as they feel (in part) like they are paying it forward.

It's important when you are getting started to build out your team so that you are prepared when something comes your way. 

I currently have an apartment building under contract that's in Canton,PA and I have been looking for lenders.

I also did a quick underwriting on what you described and the building I assume you are talking about.
