BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

There's a few opportunities to buy quads, tris, and duplexes.

Many are buying properties, doing minimal renovations to keep their crews busy, and selling with small or zero profit margins.Cash buyers are a priority.

Once I get the homeowner to sign the assignment,  do you want to be the first option to review the numbers and possibly buy ?

Things they did bad which I wish I had asked more information about:Never involved in the screening of tenantsThey recommended keys for cash by waiving the rent amount buy only collecting fees which they would get not meThe cost to evict is 750-950 yet other companies told me they will include eviction in the priceThe tenant didnt pay in full last month and I was the one calling out to them and asking questions then a few days later I get an email saying something happened with the tenant and they are investigating.You get passed from person to person every week or so.No one told me when the construction was complete and so the house was ready for a week and the post to zillow and other sites was not done.It took them another week to take pictures and then another week to upload it.I was paying 200 dollar a month electric bills while the house was vacant because they left the AC running in the empty property.

Give them all a call and see if they are willing to sell and if not are they in the market to buy.

It'll take some time but I see Anthem and all around the plant growing significantly over the coming years, small multifam and sfh's may be a good buy up around there.

In many countries foreign investors buying rentals can't get loans or loans at all. 

You could also buy from an existing landlord that has a section 8 tenant.

I was trying to work with them to buy more property in different markets and get it under a Master Lease with them but they have been really picky.
