Great choices here. 

@Eamonn McElroyIf he has a truly self-directed Solo 401k plan then the bank or the brokerage does not dictate investment choices, this plan allows you to invest into virtually anything and which is permitted in the plan documents.

It's nice to know someone will always be on the other line.In any case, making the leap to management software is a great choice.

I see that HELOC is the best choice.

It seems the seller concession is a more favorable choice since that closing cost reduction is provided all at once versus lower monthly payment by say $50-100 over a long period of time, say $10,000 concession in exchange for $50/month payment reduction, that's 200 months (almost 17 years) to break even.

Wauwatosa is a top choice, Washington Heights offers a similar feel minus the school district and at a lower price point.

It is YOUR choice but I do It…. anyone paying that little in rent will come out with the waterworks in tears to get you to not do it.

Just do your research and make wise choices.
