Either get better at estimating rehab costs or but better (with more discount at purchase) to provide a larger spread for these occurrences.

I want verification of sheathing quality, venting, along with repair estimates if needed with venting if I'm going to move forward with the deal.Much thanks.

I believe the best solution would be to classify the new purchase as investment, rather than primary, using Conventional financing, and request the lender to have the appraiser add on a 1007, wherein the appraiser provides an estimate for the long-term monthly rent.

Some of the estimates I've gotten are between 30-40k for the renovation so this could be pushing it.

It is difficult to estimate the repairs even before buying the property but you get better with experience and you can hire a contractor to help you in the beginning or get help from other investors.How did the 70% rule work for us in Sudbury:70% x $850,000 - $250,000 = $345,000 MAO (Maximum Allowable offer)Since the seller was asking for $325,000 we submitted an offer for that amount and got it accepted.Tip 1: Agents are a great source of deals for properties that need work.

Price will instead be dictated based on appraisal.To come up with the price however, come up with a ballpark estimated price.

The actual claim payments will be determined by the adjuster but you can estimate the reduction by dividing the ACV by the RC.  

AirDNA estimates my gross will be around $82k but Airbnb says a night rate of $180 is avg.
