@Sean Mcdonough I am a buy and hold so I put a down payment on one, using my line of credit (which has an interest rate like Hard Money) and then I took a home equity loan on another rental and paid off that down payment.

proper notice to enter is usually defined by the state as 24 hours notice. some states require 48. that is your starting point. that being said, coming through with a high amount of showings can be considered as disrupting the tenants right to peaceful enjoyment of their home. if you plan on coming through with one or two, you should be ok (legally) to give tenant prior written notice and come in regardless of their objections. if you think it may take multiple showings, you are likely better off to work with the tenant to set up a block of time for an open house. in extreme situations, you can consider offering a gift card to a local restaurant or movie theater to get them out. the tricky part is striking a balance between what is legal, entering with proper notice, and what is fair and reasonable, since the tenant can purposely leave the house an extreme mess to make it harder to re-rent, badmouth you to potential renters, and may even try to refuse entry. how you approach will depend on your relationship with tenant.

My husband and I will be renting to two college kids who, do to their age, do not have a credit background and (since they have retail college jobs) make $50 less than 3x the rent (net income).

A title search and credit reports have been pulled, there are no judgments or liens. 

Well, their credit Is already trashed due to the missed payments.  

Anyhow it feels good at times to help them keep their place,  especially the ones who truly deserve it and would face almost certain foreclosure, thing about the loss equity they lose, the credit impact for several several years to come. but we can't help all of them unfortunately our of hundreds of thousands in virtually every state across the country, but we try.

Does anyone know the benefits of having business credit in Real Estate.

I have credit in the low 700s and am looking to make a large down payment. 

My credit score is only like 670 which is below what conventional loans like to see and I only have about 3 grand to my Name.

If it is in fact just the baseboard that needs to be taken care of, then maybe it might be worth it to do it yourself after taking the training...but at the same time, you get a $1500 tax credit from the state for each unit you get lead safe compliance on...which would typically be enough to cover most of that work and the inspections.
