My concern is that I might be over leveraging myself if I try pull out a 20% down payment for a DSCR loan.

My main concern is not being able to cashflow the property using the LTR route.   

They are people and have needs/concerns too.

(I have a special needs trust for my son so have dealt with the complexities.)My bigger concern would not be your liability exposure but doing something that could potentially endanger the support benefits your brother is entitled to.

Also, when it comes to these infrastructure items you are concerned about, learn more about the "options".

I had similar concerns as a noob 16 years ago, what if I can't find a renter.

I am very concerned.

The only concern we run into is occasional foundation issues near the river, towards the south east side of town.

I appreciate and welcome any thoughts, concerns, or ideas!

Take for example the lack of productivity where construction projects often experience time and cost overruns, rework or quality concerns.
