The value I estimate is right around $340,000.

We estimate that the basement will cost approximately $30,000.

Then you need to learn how to calculate rough construction/rehab estimates. 2) Learn to Market.

Many lenders, including my group, offer a DSCR product to refinance on the back end as well.Before taking out a loan for a BRRRR project be sure to calculate all carrying costs (taxes, insurance, utilities, HOA, loan interest, etc.) to ensure (i) you have sufficient cash to cover monthly payments for at least the duration of the project and (ii) your estimated rent after repairs is at least 1.10x PITI (monthly refinance loan payment principal and interest, taxes and insurance).We have a proprietary BRRRR cash flow calculator tool that we share with our clients to help reliably assess costs and returns for these types of projects.

I am looking for rental properties in Tampa, FL, and I am having trouble estimating expenses when analyzing deals. 

Take this 💥just-closed renovated property for example💥:With my query of "22757 Charlemont Pl, Woodland Hills, CA 91364 5/4/2400-3050,0.6,300" we get an ARV Estimate that is ~4% off, and I picked this at random just scrolling through recently closed in my areaAnd the Market Stats $/sf of renovated property in that Zip Code matches up pretty well, so I know the ARV estimate is realistic:You can also run Agent Stats to find/get in touch with the real top-agents in that area so you can triple-verify everything and/or list it with them when you are done.With the above, I am able to quickly vet every new deal that comes my way and spend more time on the good ones.

On-site evaluations allow you to examine the property's condition, identify potential difficulties, and precisely estimate renovation costs.

Need help with figuring out how to estimate rehab costs and how to figure out what’s the best price to buy at.

Its not worth trying to collect it each month, the time and hassle, for the little amount of difference it will be over a good estimate. 

Estimated lender, underwriting fees are around $4,800-$5,500 if on the lower end of the purchase price ($100K and below for example).
