I feel like value-added opportunities would be easier in SFH over MFH for resales because families would purchase SFH differently from MFH which could be something to keep in mind in the long run as a safety net if you needed to sell because renting wasn't sufficient.

However, the 11pm footsteps/ moving noises above you while your trying to sleep is starting to get real old.

The formula for calculating DSCR is straightforward:DSCR=NetOperatingIncome(NOI)/TotalDebtServiceNet Operating Income (NOI) represents the property's income after operating expenses.Total Debt Service includes all debt obligations, such as loan payments, property taxes, and insurance.A DSCR ratio above 1 indicates that the property's income is sufficient to cover its debt obligations, while a ratio below 1 suggests insufficient cash flow to cover debt payments.Lenders usually have specific DSCR requirements, with higher ratios indicating lower risk for the lender.

If you’re getting a bad feeling before they move in you probably won’t sleep well at night while they are in your property either…

If you are in an expensive state, having a separate LLC per property might be too expensive to justify unless the equity in a given property is sufficiently large.

Better to have more cash than less, for sleep's sake

If you show sufficient W2 income you should be fine. 

@Arthur LeaoThe Roth IRA likely does not factor into your strategy as you have described it.The Roth IRA is not sufficient to purchase a property outright or with a non-recourse loan.The Roth IRA cannot be combined with personal funds to create a deal, since it is not sufficient to do a deal on it's own.It sounds as if you want access to the income.While an IRA may invest in real property, doing so is a way to diversify the IRA savings, not a way to bring that IRA money into your real estate deals.

I do sleep in my living room.

The contingency inspection was sufficient for me as a buyer.
