Most of my renters are nurses, engineers, and tax payer funded employees (Government workers). 

I love Mt Ranier, but the property tax rate is crazy.

. - Fortunately, our transparent systems allowed the owner to catch it:)- Full transparency - we would have never caught this honest mistake:(An owner also needs to be involved to approve & fund large expenses: maintenance, property tax & insurance payments (if they want to be more hands off), evictions, etc.A great PMC should also have a chat with you annually about your future plans for a property and your portfolio. 

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

On property number one, I would cash flow $750 a month after mortgage, taxes, and insurance if I also rent out the unit I live in.

Credit is a factor as bad credit may limit options, or may have the lender require you to put 10 or 20 years of taxes and insurance into escrow. 

A 1031 exchange would use all of the tax in the purchase of your next property.

Typically, the adjustments I see on appraisals for basements are more flat rate adjustments. 10k is usually the number I've seen.What stinks is that there are a couple of model types that have below grade space where the builder, I'm sure, was trying to lower the taxes by having it below grade so the county wouldn't count that space in the assessment.

Said it was one of his tax clients & would not give me their name.

At a high LTV your leverage will be magnified.If your cash flow really is break even (I have my doubts) then with the magnification resulting from leverage, you could produce a fairly good return (ROI from leveraged appreciation, equity pay down, tax benefits).Good luck
