Contractors being contractors, it took about twice as long as they estimated because they didn’t have enough people working on the house at any given time (usually only 1 or 2).

If you provide more details of the property (purchase price, estimated rents, rehab estimate, expenses, etc.), people may be able to answer your question better.

I see people paying around Zillow estimates (Bad idea in my opinion), I see investors purchasing right around the ARV, but...

Once I get them up to $500, cap rate becomes 16.7%, cash ROI is 49.9%, and annual cash flow is $10,916 ($113/month/door).Are my estimates way off? 

.-3% down would be around $4,500 down payment-$14,000 savings for 12 months mtg pymt expense used as needed to get the ball rolling-The properties I look at probably need $2000-$4000 in renovation expense-Estimated insurance would be around $120/mo and taxes around $250/mo which is included in the monthly total I came up with: $1166 roughly.

What I usually do is hit google for lenders, accumulate about 15 names/numbers/email addresses and then contact all of them and tell them what I'm trying to put together, the best one to deal with usually presents themselves fairly quickly in my experience.

You still have to worry about market rent rates dipping below your expenses, but even then, in a house hack situation it's still likely to beat the alternative: paying rent in an apartment and not building any equity.If you're looking for rent estimates in your area, I've found Rentometer to be the easiest to use to get a quick estimate.

I've estimated $5k for repairs.

I have a motivated seller who is a realtor the property is in a good area the property has fire damage and has to be fully gutted, How can I estimate the cost of a full gut?

For instance, I am estimating the rehab costs myself (without contractor experience, except book knowledge), and new to bringing a partner in with my LLC to finance the deal.
