So tapping the heloc prior to sale will not save you taxes. 

I have no prior real estate investing experience, although I have bought and sold our personal homes a few times.

I would like to purchase property here to earn rental income.I went through couple of location and found that rental is very low compare to buying price.E.g.

Prince George's has a slew of challenges compared to Montgomery County and Alexandria and Arlington County near by.

There's not many duplexes in the area to compare it to, but after seeing what duplexes are going for in the metro area just north of this city, I'd say this price seems very fair.

That may be the monthly rent for houses and apartments in the area which would not be comparing apples to apples.

Plan to presale 70% of 400 commercial condominium units prior to construction to gross $150MM, just like we did in the previous similar project.The only missing piece is to have a JV or investor willing to show prove of funds needed to process construction loan, around 25 to 30%.

Itll be valued by comparable sales.Second you’d need to look at newly rehabbed duplexes in your area to see what the value is, then you’d need to rehab it to that standards.

So i did some math using trusty Excel comparing two 5 year plans - 1.

Not many comps to compare to.
