I find it difficult also, since my schedule as a RN and being a single mother doesn't allow for me to drive around looking at properties with agents.

Proving that might be very difficult or impossible. 

I also specialize in flipping Tax Deed Land Lots, Multiple Choice Offers and Seller Finance Rentals where both the Seller and the new tenants pay me which leaves me with a little cash flow while I wait for the mortgage balance to go down and the property value to go up during the 1 to 3 yr Seller Finance period.

It could also allow you to finance the property more easily, as you won't be dealing with the pre-repair value and condition issues that may make it more difficult to get financing.

In my area it is difficult (not impossible) to purchase MFH and make it work long-term, as suitable properties are in high demand and bargains are not to be had.  

To keep credit score high you can only use 30 percentage of available balance so for you to use 50k credit card you have to have 150k in available balance.

I specialize in Wholesales, flipping Tax Deed Land Lots, Multiple Choice Offers and Seller Finance Rentals where both the Seller and the new Lease Option tenants pay me, leaving me with a little cash flow while I wait for the mortgage balance to go down and the property value to go up during the 1 to 3 yr Seller Finance period.

The market I live in 1% is simple, 2% is very difficult. 3 of my units that rent for $650 each have all-in (purchase+rehab) of $48, 45, and 42, which works out to 1.35, 1.44, and 1.55, respectively.

If it is a tenant you have had for a while and is never late on their rent and they happen to have run into difficult times this one month, that's a different story and a different strategy.  

Now granted, it is difficult to hit that 1% rule sometimes ($1,000 in rent for every $100,000 in sales price) but we definitely still have positive cash flow places.
