How long would it take to pay off? 

@Samuel Choi, PropStream is likely your best bet if you don't have access to the MLS, but you'll have to pay for a subscription. 

I will make about 10 to 12k on this one he will make about 60k without putting up a dime.4. fix and flip  he put up 10k but we had to remove the tenant so its under rehab now.. same spread as the first one  he will get his 10k back and make about 30k I will make 10 to 12k for loaning in 100k for 6 months.. 5. cosmetic flip  cant recall the numbers but this one i funded 100% and its about done I will make my 10k and he thinks he will make 15 to 17k on a 30 day rehab prime area of his little berg.I also pay all the insurance he has to pay UTLS though and he has to put up EM which you know the mid west its a joke 200.00 bucks or 500.00 bucks..

These are all things you need to do some homework on and figure out.In terms of BRR and flipping.Flipping makes you more money now.But BRR gives you the opportunity to invest, recoup your investment, have heavy depreciation tax write offs & build a portfolio which PAYS YOU IN YOUR SLEEP.You only have so much time to work, but the need for housing will consistently increase as our population is outpacing or supply of housing year after year.

Full time flight nurse and pay/schedule is allowing me to dabble in the world of real estate.  

If you prefer something with less immediate work and are willing to pay a premium for a newer property, the new development could be the way to go.Good luck with your decision!

If you are the LL, either an attorney can write one up pretty quickly if it's a complicated lease with special provisions, or your State Association of REALTORS should have a promulgated form you can use (I've had people pay me $150 to write on up for them in Texas where I'm licensed). 

One tenant is month to month, paying $2000/ month and the second tenant has a lease till next Feb 2025 at $1700/ month.

That way your tenant pays your mortgage.  

Once the buyer moved in he did not like install, equipment, timing and refuses to pay for the equipment.
