I have one SFR rental, and was just curious, can I combine the remainder of my VA entitlement with seller financing?

If you try to combine the two then you may skew the results and get into something that is either not good, or not safe, or both.

Consult with a specialist (watch Podcast 109 and talk with @Scott Smith) - you might be able to combine the operations LLC with the flipping LLC into one, but is likely to be better if you have an LLC just holding your flipped properties.

With modern technology lenders and auditors are able to fully audit their loans using AI and machine learning -- rather than looking at a few percent they are able to analyze them all.

In my market I usually see something like 10% of rent, max of $120/month.Electricity, Garbage, Water & Sewage are combined to 28% of your expenses. 

At first blush I'd say a NPV calculation combined with some sort of comps to get a price/unit is a good starting point.

In the end, combine all of the above and the yield doesn't look so attractive after all.I think we need another plan :)@Dmitriy Fomichenko - chime in.

The combination of those searches, along with my own monitoring of Zillow, realtor.com, and Trulia seems to be getting me pretty up-to-date MLS information.

Neighborhood looks beautiful with all these magnificent, modern-looking apartment structures here in Koreatown, Los Angeles. 

This is big and combined with the gain exclusion is essentially a double dip of tax savings!
