I'm not underestimating the work and unique set of challenges that come with it by any means.

6) How do they warranty their work and how can it be legally enforced?

But the IRS allows this deduction to both of us, due to them taking shortcuts in their auditing process.

Over time, they get that its not easy and a lot of hard work and eventually quit.   

I also ran 7 full marathons in one year because she was putting in 18 hour days and I could only drive Uber for so many hours after work and needed something else too do.

That sounds like a lot of work and I'm sure he would prefer to avoid that work and just sell it for $1.9m or $2.0m.if I were to buy it from him, to get to cash flow neutral I would need to increase rent on all 6 units to market rates and my monthly payment would need to be close to $6.2k/month, which would be $100k down payment, $1.7m loan with seller financing at 2% interest rate and flexible ballon payment.What would you do if you were me? 

I think that’s why I don’t have more properties, because it has to be a great deal right from the get-go, and that usually means it needs a bit of work and is also dated, but a solid investment.

Both are excellent platforms which save people immense amount of work and tme by compiling all the critical data you need in 1 place but there leads are way behind the county recorders/courts/notices i.e the source of most motivated seller leads.

All help is appreciated and I feel really bad because my other tenants go to work and have children that go to school and they are not able to sleep properly because of the loud music. 

Another option is to split the cost based on the number of occupants in each unit but this also means you'll need to adjust the charges as tenants move in/out, so it requires more work and I wouldn't recommend it.
