I'm starting to add to my rental portfolio and looking to see if I should switch to electronic door locks or traditional key & lock......

If I have a Solo 401k funded at $200k and a traditional (company ran) 401k funded at 200k also, can I take $50k loan from each to have $100k for a downpayment on a rental property?

Stuff inside the loop is traditionally worse numbers that stuff further out as most people feel the urban core has less risk and greater appreciation so they'll pay more for it. 

That could certainly be traditional basic key locks, key locks with a master key through a service like LandlordLocks.com, Schlage SmartKey system, or even the more basic, non-smart lock variations that most of the major lock companies offer as a parallel to their full Z-wave/Zigbee variants, often at 1/2 the cost. 

It would have an ARV of around 1.2MM and other homes are in that range but are all traditional construction.  

That settlement fee can go up if a traditional or hard money lender is used, but it is based on the amount of paperwork the particular lender requires. 

You don't have to have a long term lease in this case but the amount you can borrower is based on the 1007 income of the property if it was rented as a traditional rental. 

The two, one families have traditional mortgages.

If the house is not built up to flood plain codes any end buyer using traditional financing could be on the hook for flood insurance costs in the $9,000-$10,000 range.From what you described has been done, I believe you would have to raise the structure the 2-3' necessary to get it out of the flood plain.

I'm looking into creating a real estate company that makes home ownership affordable and simple for individuals in Detroit, Michigan who may not qualify for a traditional mortgage- or who THINK they may not qualify and the renter who has been renting for 3 years for $650 and is ready to own a home.
