With a mortgage of ~3.2k and monthly fees/taxes/maintenance being about 1k, it looks like these properties would turn a cash profit in the first year. 

I would guess that you will be at $2000 a year or so.

Most of them have been from newer accounts with very little history, so my guess is theyre bots or part of some lead-gen scheme.

I've dabbled in real estate for the last 15 years and have made it work for me however, I haven't made it my full-time gig yet.

About 40/60 this year.

DEAL BREAKDOWNEMD: $50,000Sub-To (with a 3-year balloon): Mortgage takeover is $5,900/month.Purchase Price: Agreed upon variable price for 3 year period.

As added insight, we're a direct lender, and we go off the 5 year treasury. 

My real estate agent, who has a long prior career history in construction, seems to be happy with both the properties and has inspected them in detail and also been under the crawl space noting new plumbing, electrical and foundation sister-in-law beams too.As mentioned it is looking very likely the current buyer will not meet the closing deadline at which point I am next in line and have got price agreed with the back up after a few phone calls today. 

We lived in that house for almost 30 years prior to returning it to a rental property and we've NEVER had cockroaches of any kind.I'm wondering if they might have come in on some of her moving boxes.Regardless, we have a pest control contract in place, and I've already contacted my technician.Should we be worried about this tenant, or am I just over-reacting?
