@Ijeoma P. working multiple brokers is tough...sure, the first call probably went well, but this is a relationship business...I've sourced 7-deals this month and none of them went to folks that were running the broker circuit.

What is the source of this data? 

In either case, the remedy to market knowledge is talking to more investors and RE professionals (PMs, agents, even contractors can be a great source of info) in your market as well as reading whatever information you can on the areas.

Hi Ryan, my start-up, Awning, uses AI and big data to help buyers source investment properties.

Can you share where your next source of capital is coming from that you already have the funds to purchase the next one?

That might be one way to go if that is your only source of cash to start your REI.Also, some plans let you borrow against your retirement account so you aren't actually penalized (by the IRS).Good luck.

Will I need to buy new window units with a heating source or can I provide future tenants with space heaters?

., cash out 200K, buy a 2-plex for 200K for "cash" to make up for the negative CF of the source asset. 

Under the sink, with a screwdriver lightly punch the corners look for rooted wood.

Developing systems to source solid off market deals will help open doors to other things you need to ultimately be successful.
