I know another option is that some towns (town specific) within the state offer some low interest loans for new septic systems.

The two vacant units are as follows:  One just had an eviction, the other is vacant and could use new carpet and paint.The area is blue collar and low income.The buildings themselves are 6/10.  

And finally, if they used a traditional P trap, you could buy yourself the extra room for appropriate slope with a low profile P trap.

In other words, we’ll need to lock in a rental before we close on our primary home but we’re relatively income poor, especially when most LL’s want 3x monthly rent for income, while at the same time we’re relatively asset rich with very low overhead.

I opened an account with Lowe’s and they mentioned something about anything over $1500.

., with min loan amt of 50K at 12% for a renovation (Fix/Flip) package...then following the BRRR (not sure how long their seasoning period is...but I'll ask) we can do a refi at their 6.1 conventional rate.Conventional loan: McGloan, 30 yr fixed rate, 4.8% (not bad)Im concerned with interest rates going up that perhaps we should lock in that low 4.8% rate (conventional loan), and pay out of pocket for the renovations ourselves?

I am analyzing a low-income rental(s) deal I stumbled upon yesterday. 

If you're a veteran, you're eligible for VA loans that have a really low downpayment requirement.

I was thinking about 10%-15%, but in some instances that seems so low in my mind.  

At $5K that is probably going to be a 2nd position note or a first position note on either a very low end home in the hood or way out in the middle of pudunk.
