I will add one important fact here since you have a preference for Roth funds: In case you have a Roth IRA already, you are not able to transfer this to the Solo 401k.

People would probably prefer a duplex because of privacy, and a newer duplex because of lifestyle/lower maintenance. 

Is there a preference for lenders that the buyer has a W2 income ?

Great book that talks about investing in a different light, not giving you strategies but looking at it from the reader's relationship with money and how their psychology plays into their preferred methods of investingGino

However, the rental market in Canton has been relatively strong, and I believe there is potential for decent rental income probably $3500, even if it doesn't meet the 1% rule perfectly.Cash Position: My cash position is fairly stable, but I prefer to hold onto this property long-term rather than pursuing another house hack immediately.

I would prefer a medium size company.

Has anyone found lenders (preferably credit unions or small local banks) that do HELOCs on investment properties, or are okay with a tax return that shows income generated occasionally on a 2nd home?

My contract does not have early lease termination clause in it and I am in Tennessee.My preference would be to give her until end of August and start showing the property right away.Otherwise I have to wait until September to start showing the property.Thanks

To choose the best rental strategy, research local regulations, lifestyle preferences, market demand, and property features.
