I encourage you to look, but I would wager that you'll find 3-4 unit buildings and larger complexes to be more your style in and around Boston. 

I am interested in single family homes for wholesaling but later I would not mind buying and holding small apartment complexes as well.

Paid insurance bills on 3 new properties.Worked with my insurance agent on an apartment complex deal that's almost wrapped up.Spent 30 min on the phone with PNC due to an online banking problem.Copied some keysVerified the closing date on a rental for @Doug Reed Now its time for lunch.

This is part of the complexity.  

The one I rolled in was hard to refinance because of a high non owner occupancy ratio in the complex (too many renters to owners).I know going forward I will likely have to do shorter loan lengths (because I am over 4) and am fine with that as long as the numbers make sense.I would go with 30 year mortgages with traditional loans when offered on your first 4. 

In more complex transactions it may require an attorney who takes 20%.

Hello Karen,my definition of CRE is sweeping.Hotels/Motels, Gas Stations, Office Buildings, Retail Buildings, Mixed Use properties with one store frontcan be CRE, Parking Facilities, Hospitals, MFH's, Industrial properties, land defined as commercial by town, Automotive, Restaurants, Day Care, Self Storage and many more.As PM I would purchase an Apartment Complex +25 or if possible an Office building.

You can always start off with one (1) 1031 Exchange and then decide to drop the last few sales into a new 1031 Exchange if they are not selling quickly.In my opinion, how you structure your 1031 Exchanges will depend to a large degree on what you want to reinvest in (i.e. how many properties, what type of properties) and how flexible the seller is willing to be.The more properties and/or 1031 Exchanges the more complex the deadlines and identification processes can become, but they are done all the time.It is also possible to combine a regular Forward 1031 Exchange with/into a Reverse 1031 Exchange.

You need to calculate in permits, inspections, possible unforseen repairs.I am able to do this because of my experience as well as a very complex spreadsheet I have built over the life of my investing.

I know less about the heloc and it sounds more complex.
