Also enabling them to rollover IRAs and old 401ks into a Solo401k.

Two huge points you are not mentioning: the up-to-$50k loan that can be taken from the SD401k for any purpose, and the fact that the SDIRA requires an LLC to enable checkbook control (which is the only way I'd invest due to convenience, speed, and lower custodial costs), whereas the SD401k does not need an LLC.

This will enable you to know what you'll make (% wise) so you will be more consistent.  

If you zoom in with this enabled, you'll get the tax parcel number for any property.

It also allows you to set multiple passwords that enable different cameras - so everybody can see the parking lot and laundry room, but maybe some areas are more restricted (IE, a tenant can see their own entrance only).

I believe that margin is really the important part, so taking that tax shield into your calculations gives you absolute clarity that could enable you to offer just a smidge more to close a deal.That's my theory anyway...

Based on what you wrote, I believe you have two primary goals.A dependable passive income that outpaces inflation and you will not outlive.Equity accumulation to enable additional investment property purchases minimizing the total capital required.If these are your goals, I recommend following the process illustrated below.In this post, I will only discuss location selection.

If another record is found the system automatically notifies the lender through an alert to delay pending further investigation.Most importantly, the tool retrieves the information allowing users to identify the entity or entities perpetrating the potential fraud.It can be used to screen already closed short sale transactions enabling the lender to continue to watch the property for a period of time and generates an alert for any subsequent loan closed on the property, the original short-sale lender and the resale lender.Moreover, it provides post-closing alert notifications, reviews of sale terms for violations, and alerts the new lender about potential for fraud in the dual transactions.Retrospective short-sale analysis helps detect fraud, assess pricing-method accuracy and pinpoint problematic areas to avert future losses.

Enables me to drive by everyday on way to work and back to see what's going on.
