My main interests will be in fix and flips, BRRR, and buy and hold.

One suggestion to consider as I mainly do BRRRRs as well- find a local bank or credit union in the area you plan to buy that offers construction loans.

My main job is running my investment holding company, so I'm familiar with public and private market investments but new to RE. 

I have a degree in civil engineering and 15 years construction, site development, and short term rental experience and am looking to shift my focus/career towards real estate development, mainly raw land although if there were a house on the property could include fix and flip.I plan to purchase 50+ acres of raw land with 1000+ feet of road frontage, have it surveyed and split into separate 5+ acre parcels for re-listing.

However, my main question is how investors determine a reasonable target, especially since some investors with access to higher capital are able to target projects with higher returns than the easily accessible passive or traditional opportunities. 

Regarding costs there are a lot of factors considered but to give you a ballpark idea, here is a brief scenario: Our main office is based out of Cherry Hill NJ, a typical 3 bedroom row-home lead-paint inspection in that area would cost on average $450, however we can service the entire state of New Jersey (North Jersey office in Montclair, NJ). 

There are plenty of commercial buildings in Phila but they have 2 main concerns which deters investors.1.

Hi Ryan, Sounds awesome, me and my husband are doing our investments together also and really love to connect with more couples :) We are new to these areas and looking for rentals that works with BRRRR which is our main strategy, did you try to find BRRRR or do you prefer flips and STR?

They are major BRRRR projects with the main exit strategy being to hold as medium term rentals.

But my long term is rental mainly.
