Early Investor seeking multi-family advice in the Dallas area

[Pundari Pothini]

Been playing the buy and hold SF play for some time now. Flipped a few properties, have a small SF rental portfolio and fairly happy with my investments so far. Recently sold a property and a business which returned some decent $$. I'm trying to invest this multi-family income generating properties. Looked at passive investor opportunities and concluded that it does not suit my style. I'm more of a build something and let someone manage it and move on to the next one. 

Been searching the internet/loopnet/zillow etc,. and I don't think I'm ready to take on multi-million $$ properties yet because this involves partnerships high investments. One of the ideas that I'm evaluating is to acquire a small piece of property within the city limits near a train station of local towns such as Farmers Branch, Carrollton, Lewisville, Plano, Euless etc,. Need to be able to build either duplex/fourplex or small apartment building.  I'm looking for a GC that can help evaluate costs before I acquire a property. I'm also looking for a commercial realtor who can help locating such property.
