From there, it requires the ability to conduct underwriting the highest and best use of a planned project, which requires a pro forma built by the user or acquired from a competent 3rd party. 

I think that the ability to get paid when you need to do either one of those is not talked about enough.

The ability to turn single-family lots into duplexes or even split lots for separate units can significantly boost rental income and property value.

After a year of canvassing for a veteran financial services executive whose values align with our mission, we have found a remarkable fit.

PROS of a Solo 401(k) with no Custodian: 1) Freedom of checkbook control, ability to more easily move funds in and out of a bank account in the name of the Solo 401(k). 2) In some cases, lower fees. 3) Ability to more easily link your Solo 401(k) to bank account systems like rental property management systems, or if investing in real estate syndication platforms. 

If there's a family member or friend in a similar situation, and you can both align on the initial plan (location, home type, price, usage/occupancy, etc) you can pretty easily get a co-ownership agreement in place and even a joint mortgage.The benefit here is it might open up your ability to buy a larger place in a nicer area which could lead to a faster rate of appreciation and overall better living environment. 

Other types of sellers that are making deals easier to get done are those with assumable debt available, and sellers with the ability to seller finance there properties.

From an investment standpoint this reminds me I believe of a Bill Cosby story line I believe.  

You may have more ability if you have any previous 401k's from previous employers?

@Collin Luckett  Just adding, if you have the ability to fund with your HELOC, it would be far cheaper than PML or Hard money.
