Is it ever a good option to pull from your 401k to make a down payment? 

A significant down payment reduces the risk of default.

Keep in mind you put $30,550 cash in as a down payment.

Here are the metrics that I would use in the five categories you cite:  - Household Debt Service Payments as a Percent of Disposable Personal Income (TDSP) - Mortgage Debt Service Payments as a Percent of Disposable Personal Income (MDSP) - Consumer Loans: Other Consumer Loans: Automobile Loans, All Commercial Banks (CARACBW027SBOG) - Student Loans Owned and Securitized (SLOAS) - Consumer Loans: Credit Cards and Other Revolving Plans, All Commercial Banks (CCLACBW027SBOG)I put in links rather than images since BP tends to delete my images for some reason.

If the rents aren't covering the payments, they may be willing to sell at a loss (or break even point) just to stop the flow of money.

Your local PHA may also have resources to help match landlords with eligible tenants.The PHA must approve the lease agreement, ensuring it complies with Section 8 rules and rent limits.Pros:Guaranteed Rent Payments (sometimes even 100% based on certain tenant criteria)High demand for Section 8 rentals, which can reduce vacancy periods.Many Section 8 tenants prefer to stay long-term, reducing turnover rates.Cons:Properties must meet and maintain HUD's health and safety standards, which can involve additional maintenance and inspection requirements.The PHA limits how much rent you can charge, which may be lower than the market rate in some areas.Tenants must qualify for Section 8 based on income level and other factors, which may limit the pool of potential renters.Dealing with government agencies can sometimes be time-consuming and bureaucratic.In summary, converting your home into a Section 8 rental can be a good strategy for attracting and maintaining long-term tenants due to the stability and reliability of government-backed rent payments.

I used a HELOC on my home as a down payment and around $30,000 of my own money over the course of 6 months to repair it.

It would be interesting if Section 8 payments for your area were higher than what you say is average for the same bedroom count for non-voucher holders.

My parents brought the down payment, while I paid the closing costs.
