Additionally, my area has an abundance of 4-family properties in those in-between areas where a would-be house hacker can benefit from the four rental income streams (instead of just two if they bought a duplex) in order to help stay within the DTI requirements.

The Niagara Stealth advertises it's ultra-high efficiency @ 0.8gal/flush.I pay for the water in my rental units, so I was looking for something that's going to cut my costs on water, but also doesn't clog and need constant repairs.What do you guys think?

I own 2 older townhomes, and there are constant assessments (including $6000 each for roofs) and fee increases.These issues aren’t always apparent from reading restrictive covenants and seller disclosures so it’s important to verify with the HOA.
