You have a "little starter house" that is worth $350k if you sell it now. The alternative is you could have (350+45=) $395k tied up in a rental house yielding (2,000-900=) $1,100 in rent before upkeep, property management, termite policy, umbrella insurance, etc. So maybe *very* optimistically you profit $750/mo or $9,000 per year if there's nothing else wrong with the building. This house utterly fails the "1% rule" landlords have used for ages.
$9k a year on a $395k investment is an ROI of 2.28% before taxes. That is not good for a concentrated, risky, and time-consuming investment. You're earning less than the yield of BND, a fund the holds mostly risk-free, hands-off treasuries. Also, from the rent-price ratio I can tell you're invested in an area where most people (who set the market price on rent) cannot afford the purchase price of a house. I would unload the house immediately and invest the proceeds per my IPS.
