Make sure that the monthly payment obligations showing up in the credit report aren't excessive.

Do the properties then become untied to the now closed SDIRA, in which I would have the liberty to use excess cash as I see fit for my business or personal use?

You may wish to confirm that the new 401k provider will handle the ongoing compliance support such as any required 5500 filing (e.g. 5500-EZ for a one-participant plan with assets in excess of $250,000), any required tax reporting (e.g. 1099-r in the event of a distribution or in-plan Roth conversion), mandatory plan updates and amendments, etc.4.

This almost always necessitates the NRA file a 1040NR to reclaim the excess withheld, further adding to the compliance structure and cost.A lot of hedge fund managers don't like to have NRAs come into their LPs specifically because they find out about these obligations during tax time and don't like what it does to their compliance bills.A "blocker", i.e. establishing a US C Corp between the NRAs and the US investments, does solve this problem, but again, all factors need to be considered for a holistic approach -- minimization of US tax liability, Canadian tax liability, and compliance fees in both countries.

The tenants in questions and the tenants downstairs have discussed this for 2 month regarding smoking weed (which is illegal) and excessive noises.

However, the excess cash flow from that rental just goes to pay off that credit card bill.  

If the suspended losses are in excess of the total gain, the remaining suspended losses will then offset ordinary income.3.

Some of the pricing sounds excessive and doesn't sound like something the Tenant would be responsible for.Based on the list, it sounds to me like the property had some maintenance issues before these tenants moved in.

Total gross income for this duplex is just over $20k per year.Do you feel $91,500 in coverage is excessive?

Anyone who has taken a thermodynamics class will understand when I refer to the oceans as a "heat sink" - that is, they absorb excess heat when the atmosphere is hot and give off heat when the atmosphere is cool.
