@Chris Seveney as a real estate broker, more than a 100 on residential side and ~30 on commercial.

I am new to the commercial real estate investing world but have done a little dabbling with residential as a wholesaler.

I'm interested in multi-family investment and want to buy a residential multi-family (2-4 units) to live in one unit.Ideally in Montgomery County as I live in Rockville (or PG county/Baltimore)

The companies that market themselves as "garage door companies" (residential) also almost always do commercial stuff as well, such as what you are looking at.

When wholesaling vacant residential land (city lots or larger residential parcel in rural areas) how long is the due diligence period?

We are looking to buy a residential, multi family unit.

A lot of investors provide comps (residential RE) but I avoid doing it because it's like telling them how to do there job.

However some of the "easy parts" of residential change like financing and the term of the note.

.), I'd recommend that the residential units fully cash flow the loan as my experience is that mixed use properties are tougher to finance as most lenders tend to prefer one or the other and something in the middle gets more difficult.For example, and granted I don't know anything about the area/neighborhood, I would expect this property (https://www.realtor.com/realestateandhomes-detail/111-NW-Har...) to be easier to finance than the mixed-use property you mentioned.
