I am 56 years old and would like to increase my income and plan for retirement.

To make it simple the two RE jobs, absolutely no weekends available (which of course leaves a couple weekdays free).

What happens to value if you calculate the forced appreciation from the increased rents?

If everyone has available units, you will probably want to increase your vacancy numbers.  

Taking a small loan to add a greater value to this property is good debt and will increase your net worth.  

I don't like to plug in uniform, base rent increases, etc because you may be buying way below market with massive increases initially then subtle 2-3% across your ownership, etc.  

This could even be two years in advance if their goal going in was to rehab, increase NOI, and then sell.  

My investment home (SFH) which is currently rented out has increased my DTI significantly.

Following is how the ROBS 401k works: Because you directly rollover your IRA or former employer 401k, 403b, Keogh, SEP, SIMPLE, or other eligible account, to your new ROBS 401k  plan, which then funds your business, you incur no taxes or early distribution penalties.Unlike traditional 401k plans that allow for a 401k participant loan, that is, borrow up to 50% of the account balance not to exceed $50,000, the ROBS 401k for business financing plan allows you to use all of your retirement funds to fund your start-up business.The ROBS 401k funded corporation allows you to draw a reasonable salary from the business.ERISA 408(e), and ERISA Reg. 2550.408 list information regarding the use of 401k funds to invest in employer stock of the employer’s corporation.The IRS formally commented on the use of 401k business funds on Oct 1, 2008 by issuing IRS memo commenting that the use of retirement funds is not disallowed but continue to be reviewed by the IRS.The use of retirement funds for business funding entails the 401k purchasing stock shares in a C-Corporation.
