You start with a base line and introduce variables to determine their effect.You can see what trends have happened if you choose to, that may be of interest to you, but that isn't what currently interests me.

I don't want to refinance because my current rate is under 5% and doing so ruins the cash flow I've got right now.

So, if you were a 'new' investor, but with your current skillset and knowledge base, and had $750,000 in net sales proceeds from a recent downleg property sale, where would you recommend investing in multifamily real estate? 

Here’s a bit of background on my current situation:I own one rental property that generates $1,900 per month in rental income, and it is paid off ($300K).My primary residence is also paid off ($288K).I’m currently building another rental property with cash ($200K).

I currently live Wisconsin and work in Real Estate.

MLS, currently looking at other ways to acquire properties.

I do have a family friend who is currently building in my market.

I'm more interested in purchasing 10 homes to have fully paid off by the time I retire, as I'm not living on the cash flow w/ current job. 

Our current mortgage terms include a late fee after 5 days, so they’re already paying extra each month and have to split the total monthly payment up between 2-3 payments when they get their pay check.

Current balance of loan is around $380k.
