I'll write down the rates below. 2.75% - 0 lender credits - $1,327/mo mortgage2.875% - $1,200 lender credits - $1,340/mo mortgage3% - $2,023 lender credits - $1,337/mo mortgage3.25% - $4898 lender credits - $1398/mo mortgageI'm leaning more towards the 3.25% so I pay close to nothing for closing costs but obviously with the estimated rent, I would have to charge $1,600 to cash flow maybe $100.

We estimate that it would appraise for about $450K now!

I have the funding available, but the only rehab estimation I have knowledge of is through the books/podcasts I have listened to. 

Listing site estimates roughly $1,700 in mortgage, insurance, & taxes with 20% down.What are your initial thoughts?

I for one will not even attempt to perform a estimated cost of repair or a ARV.

(The reno costs are a very rough estimate... just trying to run scenarios and experiment with the process).

I'm estimating it would cost $60,000 and 6 months to complete the job. 

Hopefully they will provide a good estimate on you permit fee schedule. 

I would greatly appreciate any advice you all may have for me.STATS for property & self :-Primary SFH since 11/2018-No other loans (no student loans, personal loans, or car loans)-Credit cards: 4 in total with zero balances -W2 employee Questions:-Is it better to get a home appraisal before applying for the HELOC, so I know a more accurate estimate of equity?
