In an effort to make a profit and cover all my debit service (mortgages, PM, expenses, loans, 50% of gross income); what is best to acquire; MF(s) or SFH(s)?

Rental income on the other hand, will/should come every month, with a lot less physical effort.If you have trade skills, I would advise you to buy a 1-4 unit which needs some work... fix it up/add value... rent it... then refinance into long term debit.

You will need to have all of your i's dotted and t's crossed.Of course, sometimes you just need to debit cash and credit experience.

You could use FHA loan at 3.5% down and ask for concessions from seller to cover your closings costs and pre-paids. 

Pre-paid MI?

Said your tenants could pay debit, credit, or with paypal and it could be set up to go right in your account.

It's electronic if that's how I want it; for example, when one tenant has the same amount of rent as another and I don't know who paid on time or who didn't, one (or both) have to pay electronically by auto-debit through erentpayment.com.

Make sure you put at least $200 every month as a pre-paid expense in this bucket.  

I think the LLC could work, I guess if you want it to be a business and not have the tenants writing checks to you personally, then they'd know who you are eventually anyway. you'll need an LLC to get a business bank account where the checks or ACH debit will be deposited. 

When I opened up a business checking account for our LLC, they requested a copy of the Operating Agreement, and specifically needed the listing of the members to determine who could access the bank account, get debit cards, etc.
