The other thing is condos have extra fees which will affect your bottom line. 

Is 2020 recession hapening and how will it affect the real estate prices ?

Any of these are potential red flags.Don't allow financing or a finance contingency (it can be a good indication they are selling above market value)Don't allow for your own independent property inspectionAre not realistic with their pro forma's (i.e. they don't include vacancy or maintenance projections or use unrealistically low vacancy factors)Require you to pay for any renovation upfrontSell only in cheap. low end neighborhoodsDon't accurately represent the neighborhood/property classificationDon't have consistent rehab standards for all propertiesDon't provide a scope of work for the propertyCan't provide references of repeat investorsRequire you to close before a tenant is in place

I'm wondering how the appraisal may be affected if there's window units.

Settling is tricky, because it can affect so much of the house. 

Even though the value of the house increased, did that affect rebuild costs for your area?

The refinance is key to get cash out in order to repay lenders and be able to repeat.

Andrew, if your lender did a hard credit pull then it will negatively affect your credit score.   

Nothing worse then  completing the process and you can’t refinance.Last R is repeat.  

I love giving repeat business to lenders.
