Tax lien properties

[James Gerard]

I’m brand new to everything in Realastate I recently went to a tax lien auction I purchased 2 properties the first property has 2 single family houses on the lot. Both were vacant I fixed up both houses rent 1 out and I am currently living in the other. The second property is a 4br 2bathroom 3 story house in a really good area. I am looking for some funding to get the 2nd property fixed and ready for rent or flip can anyone point me in the right direction also I have a ton of questions

Should get an LLC and transfers the houses over to it

If so what’s the process

At the auction they said the deeds weren’t marketable what does that mean

Someone please help and thank you in advance
