Your best defense is as alluded to above is buy a substantially below market.

Hi BP,   This is my first substantial post.  

They were able to solve a pretty substantial issue that my investment group was having qualifying for conventional financing.

Hi everyone,I'm new on BP,currently have my own Renovation Company,tried a couple of flips before (one went good the next not so good due to lack of knowledge on the whole REI picture).Having said that i read Rich dad Poor dad recently that led me to a "free" one Hour seminar followed to  $800 3 days one,followed by a 30k tutoring/training one year program they offered so my wife and i put a deposit and agreed to pay this on a 10 day money back guaranty contract...currently me and my wife have access to a very substantial amount of money due to a HELOC loan from our primary home,my question is..is this training/mentoring really worth the 30k or should we put that money in REI without this mentoring process?

My guess is ARV is lower than $105k and rehab will be substantial taking 3-6 months.

However to do so over time,paying out substantial money before you are in title is pretty risky.As @Rick Pozos said this doesn't sound even close to a deal anyway.

If they have been in the units for years there could be substantial repairs necessary to get them rentable.

Personally, if there was substantial savings on interest I would opt for mortgage free property.

Most banks are happy to see that and will be glad to extend you out another 5/20 which will lower your payment substantially if interest rates are the same or keep the payment the same and support a higher interest rate.Also, if your property has appreciated in value/your rents are higher, your ltv is even lower and you are in a very good position.

I have heard that this can INCREASE value of your home substantially, and also INCREASE RENT potential for buy-hold properties.
