Biggest X factor is when we did our walkthrough, we noticed basement ( unfinished) is totally flooded with sitting water ( too high to walk through) and it seems like the water has been sitting there for months.

Putting CF aside, at the end of 15 years the value of A will be ~$135k, a ~35% return on the $100k, but B will be worth ~$675k, ~175% return on your $100k.This doesn't even factor in depreciation or mortgage pay down.Let us know if you have more questions.

Even a quick ballpark of the numbers they were giving her meant a payback period of almost a decade without the NPV factored in.I told her not to do it.It would make more sense to take that 5K "closing cost" and drop it into paying off the current note's principal.

There’s too many factors to consider, including (lack of) housing affordability on the coasts.

I was mainly thinking having a higher income would be more beneficial in securing loans and scaling faster, and there could be a possibility that the market would cool off by then.

Usually price and pictures/curb appeal will be the main factor in getting people in the door.

Factor it into your rehab costs, and make sure your all in is still at or less than 75% of ARV. 

I'm just wondering if there are other considerations that should be factored in, such as incorporating the depreciable asset of the apartment structure in MFH versus mobile home parks being primarily land, etc.

Factor that in.Alternatively, could you implement RUBS to pass the heating costs back to tenants? 

It has been on the market for 134 days, so I may be able to negotiate a lower price if the seller is motivated.My down payment is 3%, and closing costs will be factored into the mortgage.The amount for principal, interest, property taxes, insurance, and mortgage insurance is around $740-$760/month.
