One of the keys for landlords is that the new rules significantly lower the number of surfaces that have to be deleaded...which lowers the cost of abatement compared to the law pre-12/1/2017. 

Are there any restrictions and risks of renting a SFH for business plus residence purpose?

@Chatree C.You will need to find a Solo 401(k) plan document provider and then you can have the funds reside at the custodian that you mentioned or at a local bank if you prefer.The Solo 401(k) provider will also assist with the ongoing compliance requirements such as filing form 5500-ez when needed, processing plan updates and  also answering technical questions regarding the rules and regulations.Regarding UDFI, this tax generally does not apply to the Solo 401(k) plans.

In the Property Disclosure -> Covenants, Fees and Assesment section, the seller marked YES to Q:Is the property subject to a recorded Declaration of Covenants, Conditions and Restrictions (CC & R"s) or other similar restrictions.No explanation notes were provided.

Condos are fine but make sure you understand all the HOA rules and fees prior to committing to a purchase.I know BP members have mix feelings toward condos, some just avoid them and there are some that’s all they buy.Also be aware you might have less Finance Options if majority of owners in Condo are investors..

Unless the rules have changed, FHA would treat you just like a recent college graduate.

PMs have different contracts, and some may be more restrictive than others in what control you have. 

Leverage is a force multiplier: It can move a project along quickly and increase returns if things are going well, but if a project’s loans are under stress – typically when its return on assets isn’t enough to cover interest payments – investors tend to lose quickly and a lot.As a general rule, leverage should not exceed 75% of the total property value, including mezzanine and preferred equity, because both of these types of debt sit ahead of common equity in payment order.

As I understand the rule of transferring into a trust, you cannot have the mortgage called if you put property into a TESTAMENTARY trust. 

There are rules about how bank accounts can be set up and so forth, but that comes down to state/local law level.
