Probably good to have one or two of these started early rather than later since the the premium will increase as you age due to health/age.

With no experience in this area I've been considering partnering with one of the following coaching/mentoring groups (Flip System or Flip Cheap Houses) does anyone have experience with these two? 

Once you get into a large number of doors (10+), I'd look into software.  

One of my clients did a rehab on a two-unit building in Bridgeport that appraised for $100k over within in a year.

I have 9 doors across the midwest and always looking to add more.

As well, It would not be legal for your agent to pay you a commission.They will be wearing two hats in your proposed transaction; one as a passive investor sharing equally in the expenses and profits, and the second, as your real estate agent. 

I'm right next door in Gaithersburg.If you don't have a property yet, I'd attempt a househacking strategy.

So now in 2024 we are two years in, 8 years to go on the current lease. 

It could be ideal for a house hack as there are two separate entrances, each with its own kitchen and bathroom.

Or if there is a 10 unit made up of two buildings, or two 'sides', I'll let an STR person take one side/building/chunk.In Montrose I have a 10 unit that's made up of a 6 and 4 unit building.
